I've talked to a few economists about this and non agree with Elon on this.

The biggest issue one person raised is how do you separate out government spending form GDP?

If a US town has a big military base, does that mean the entire towns' GDP is just government spending so ignore it?

The government essentially pays for everyone's salary in the town.

Where do you draw the line at what is government spending and private spending?

Cause if the base went away tomorrow then so does the town and about 95% of its spending, so it would be hard to include any of the towns economy in the GDP calculations if you only want private spending as the private spending in this case is almost all first or second order based solely on government spending.

Or at a more macro level. Boeing is a legitimate company but more than 50% and more than 75% depending on how you account for it, comes from government spending.

So do you just not include 75% of Boeings spending in GDP?

How much of the Boeing employees spending do you include in GDP then as if 75% of their salary is government spending and you are trying to exclude government spending.

If you allow their spending to be part of GDP then you are saying you are including government spending in GDP just as a second order event.

I'm told people still do their Phd in economics on this topic so its clearly a very hard problemm.

I don't know why people are entertaining this. The Gross Domestic Product by definition measures every expenditure, income or production of a specific territory. If you exclude government effects in the economy, you get into so many troubles.

Presumably for the same reason you hear people say things like "How can inflation only be 2%? I am spending 10% more. We need to redefine inflation!"

In other words, people want the data to speak to the government on their behalf so they don't have to. Musk is playing into that same idea.

The question if the goods basket that is used to define inflation actually reflects reality is valid though!

For example, the explosion of rents in urban areas is offset by shockingly low rents in "flyover states" and rural areas, leading to a complete neglect of the problems of urban people because it simply doesn't show up in the statistics. For many poor people, they don't have the money to buy new clothes anyway, much less expensive goods such as new cars or luxury goods - and yet these products are all in goods baskets, offsetting the cost explosion in basic staples (and not just eggs).

IMHO, "inflation" as a simple percentage metric is not a KPI that can be used - at the very least, socioeconomic strata and urban/rural differences need to be taken into account because over the last decades, thanks to rural flight the realities have separated way too hard.

The problem that the Democrats faced in the last election campaign is that they only focused on KPIs useful for rich people: stock market indices, employment counts, GDP. But that mis-focus completely alienated the wide masses who felt they're being fed lies as their reality (exploding expenses but stagnant wages) was markedly different from what the Democrats pushed.

Why? You're only trying to determine the change in value of the currency. What specific items are in the basket shouldn't matter all that much as long as it is a broad enough sample to be able to separate out the change in value of the goods from the change in value of the currency, along with it being comprised of things consumed frequently enough that you can see any change over a short period of time (e.g. monthly).

> socioeconomic strata and urban/rural differences need to be taken into account

Implying that an urban dollar isn't the same as a rural dollar? I mean, that is similar to what Musk is saying: That a government dollar isn't the same as a private dollar. But how do we quantify that? If we each throw down a $1 bill and shuffle them around, how can you tell which one represents an urban/government dollar and which represents a rural/private dollar?

The same dollar buys me a lot more food and accomodation in rural areas. To give you an example, average rent for 60 m² in Munich will easily run to 1200-1500€ a month, and that's net (so you got to add heating and utilities on top). In Eastern Germany, you can get 80 m² for 300€ a month. A trip to the grocery store is about 100€ in Munich, maybe 50-60€ in Eastern Germany, simply because the staff and rent cost of the grocery store are also much lower than in Munich.

Unfortunately, collective wage agreements, UI benefits and pensions are federally the same across Germany - that means for example the train driver in Munich barely scrapes by because cost of living eats >50% of his paycheck while the train driver in Eastern Germany lives like a king.

That's because food and accommodations are often less valuable in rural areas. Supply and demand, as they say. But that is outside of the scope of inflation. As before, inflation seeks to measure the value of the currency itself, which also fluctuates in value just like everything else.

> Unfortunately, collective wage agreements, UI benefits and pensions are federally the same across Germany

Theoretically the value of the dollar could differ from place to place like food and houses – value is just arbitrary human opinion, after all – but as currency moves freely, everyone tends to agree on its value across entire countries (and usually the entire world). In practice, you'd also find accommodations and food settling on the same value across entire countries if we had magical portals that could move them to and fro on a whim like we can with currency.

But it seems like what you are really thinking of is a cost of living index. Usually those are prepared on a regional basis for the reasons you have described. Inflation is decidedly not intended to be a cost of living index and there is no reason to turn it into a cost of living index. We already have that – not to mention that we also need to understand inflation.

You may be also implying that some people use the wrong tool for the job (i.e. trying to use inflation as a cost of living index), but in that case the problem isn't that the tool broken, the problem is that the people are broken. The question then is not "What will it take to modify this screwdriver so that it is better at driving nails?" The question is "Why the fuck aren't you using a hammer?"

Yup, that's the second problem. "Inflation" is the _only_ tool other than stonk market indices that's being used by politicians, media and central banks to judge "how is the economy?" and derive consequences, but as shown it's much too coarse of a hammer.

What's the problem? Money is just debt. Having confidence that you can call the debt at a later date is the only property that is of true concern with currency. As long as you have the confidence, it theoretically doesn't really matter which currency you use as your IOU.

Perhaps you are suggesting that those particular currencies are losing confidence? You could especially make that case about the USD right now, methinks. But if each state/city/rural area in the USA, for example, had its own currency, would they really garner any more confidence? They are still subject to most of the same whims that is giving the USD its current look.

> "Inflation" is the _only_ tool other than stonk market indices that's being used by politicians, media and central banks

Aside from the media, which I think is a fair point – it likes the headline grabbing attention metrics, that's not really true. You are right that a primary objective of a central bank is to keep the currency stable so that people remain confident in it, so it may seem like it disproportionately focuses on the value of the currency, but that's kind of its job. But they aren't even looking at a single inflation measure. If I recall correctly, the US uses around 30 different measures of inflation internally.

> to judge "how is the economy?" and derive consequences, but as shown it's much too coarse of a hammer.

Thing is, the national economy doesn't really matter that much to your every day life, does it? As long as your local economy is strong, who cares (I mean in a self-serving way, not taking pity on those affected) if people on the other side of the country are struggling? While countries do vary, typically the nation is only concerned with big picture things like keeping confidence in the currency. The actual economic issues are for local governments to sort out.

Hence the old adage of the municipal government being the most important. And municipal governments should be looking at things like cost of living indices for their region. If they aren't, it is time for some tar and feathering.

The problem is the wild disparity in purchasing power. Like, with the same amount of money at your disposal, you're able to live like a king in the poorer parts of the country - but literally struggle to survive in the richer parts (i.e. urban/megalopolises). Currencies have two functions - long term value storage (which is what you're referring to with required confidence) and short-term value aka ad-hoc expenses, and that's what the wide masses use currency for mostly as they don't have much to save.

That's something that was seen as a serious problem here in the EU when the Eastern European nations were introduced in the Euro, and the predictions materialized as expected: Eastern European countries suddenly had merchants demanding Central European prices of goods (alone to prevent Central Europeans emptying the shelves and doing arbitrage trading), while pensions and wages didn't keep up with the price increases as the economy's productivity wasn't anywhere near enough. Hell, even the industrial heavyweight that is Germany struggled with that issue (the Euro was called "Teuro", from "teuer"="expensive"), the Eastern Europeans got hit orders of magnitude harder.

> You are right that a primary objective of a central bank is to keep the currency stable so that people remain confident in it, so it may seem like it disproportionately focuses on the value of the currency, but that's kind of its job.

Yeah, the infamous "the economy should be at 2% inflation" target where everyone dances around while conveniently ignoring the effects of that on the wide masses that don't have collective wage agreements.

> Thing is, the national economy doesn't really matter that much to your every day life, does it?

Media and politicians only focus about the national economy though! You won't ever hear a national news anchor talk about some random paper mill or whatever in a flyover state. But people see that the local economy is going to the gutter while politicians and media act like everything is fine. It's literally the "everything is fine" meme [1], and that's why public distrust in politicians, media and democracy itself is at rock bottom at the moment.

> Hence the old adage of the municipal government being the most important. And municipal governments should be looking at things like cost of living indices for their region.

They can't. They lack the legal authority and the tax income to do anything meaningful, and most issues are caused on a national level.

While disparity in purchasing power might be a problem, what does that have to do with currency value? If you traded in apples instead of dollars/euros, the same disparity would be present. The urban accommodation seeker would have to pay three apples to every one apple the rural resident pays, changing nothing. This has little to do with currency.

> Media and politicians only focus about the national economy though!

For the soundbites to give a broad picture to the people, sure. There isn't enough time in the day to go into great detail. That is only presented to pique your interest, though. If it does, you're going to dig deeper. If you don't care, then, well, they didn't waste your time giving you a four year economics degree for no reason. Tradeoffs, as usual.

Assuming democracy, they have all the authority you are willing to give them. If you've misguidedly given too much attention to the nation and not enough attention to the municipality, time to fix the people (this is becoming a recurring theme!) There is no need to modify your screwdriver to make it better at driving nails (which also can't be done without fixing the people!). Just use the damn hammer already.

two things about that: First, employers do take local cost of living into account to set pay, some implicitly due to competition, but many of them explicitly adjust wages based on cost of living data from economists. Secondly your complaint about the wrong KPIs rests in part on conflating cost of living with inflation.

The problem the Democrats face is that wage prospects and social issues are segmented by level of education more than in the past. They should run on higher minimum wage, which will benefit rural workers more, and on making inclusive social views the key to social acceptance. Might be an unpopular opinion, but the Democrats won't get the sports betting crypto Joe Rogan incels anyway, so they might as well make the most stereotypical ones the symbol of how to keep you dick perma-dry.

But that's just because more people typically seek higher levels of educational attainment than in the past, so the more capable people filter upward.

In my grandfather's day, even going to high school was relatively unusual. Back then, the "less than high school" cohort was a healthy mix ranging from those with extreme disabilities to high performing people. Nowadays, there are often even legal mandates that require anyone who is capable to graduate from high school. So, the "less than high school" cohort is now effectively only those with extreme disabilities, with all the life challenges that go along with that. As such, if you only glance at the data you might think that lower levels of education have fallen behind, but in reality they've just lost the people that helped make it look better than it really was for those who struggle.

That doesn't seem like it should be a problem. Only the counting has changed, which isn't materially significant.

I suppose what you are trying to say is that said shift has revealed how bad things have always been for the disabled, and Democrats are called upon to fix the issue making it their problem, whereas it is understood that the Republicans are always of the "fuck the disabled" mind so nobody expects them to deal with it?

And yet the fiscal multiplier of money spent by the government is >1. Per each dollar spent by the state, there's a economic growth above one (btw, there's a paper that looks at many actions done by the government[0], guess which actions actually drag the multiplier down even in the most favorable estimations).

Yah, I personally don't think fiscal multiplier is a great measurement because it pushes you towards thinking about government spending in a couple of wrong ways. First of all, it's not correct to say government spending is good because it causes an increase in national income greater than the spending. The correct comparison is to what would have happened without the spending and it's both hard to figure out and not very clear that the government spent that money better than had the left it alone and the populace deployed their own cash/didn't adjust their own capital deployment to account for the extra debt the government took on in their name. This leads to the second problem with it and that's that the next thing someone who likes this measure will say is "the spending is exogenous" which is neither true or a good model of reality.

Also, looking at your paper I see the estimate range has 1 in it in all cases so I question the actual correctness of your statement. If one is in the likely range of effect you can't say spending is stimulating additional anything.

Now you've ruled out lots of other stuff though. Is loaning money "production?" Is spending for services (like, software development!) "production"? Is investing in assets like real estate "production"? All those activities create wealth!

Now you've got a definition where only primary production, like farms and construction and mining, have any value. And that's silly too.

No, all economic activity creates wealth. The idea of "spending" being separate from "producing" only holds at the microeconomic level where you are playing a zero sum game with a single bank balance.

That's just a historical artifact of when the concept was created [0]. The thing can be measured by income, production (including intermediary products) and expenditure. The government component comes in the expenditure method. Economists don't differentiate between them as they are just looking at the same data with another perspective, we just don't care.

There are numerous examples of people who appear to be intelligent, witty. Maybe they hid their darker sides (be it some authoritarian, populist, racist or otherwise objectively bad tendency). But they did hide them. But then something seems to change and they quite quickly descend into being very unlikeable. And it's not just always "ideas". It seems to permeate their entire being. The transformation includes going from being "likeable" in a broad sense, to very abrasive personalities even when you factor out their views. It's really scary and depressing. We only notice this in some really high profile cases (Musk, Notch, a few politicians...), but I'm sure there are thousands of less visible people who have done this transformation without anyone noticing but their close friends and family.

I attribute this to the amplification effect of social media has on the output from these famous people.

But at the same time I blame their slide into madness on social media because for both Notch and Musk (and I would also add JK Rowling to this list) it all started with disproportionate amount of genuine hate from well meaning individuals for stating opinions slightly outside the Overton window. I think the "twitter mob" is frankly more to blame than the people themselves, because without it, all three of them would still censor their public outbursts more than they do now after the dams of hate against them have already broken and there's no lower depths they can sink to.

That's why I think it's important to be polite even to the assholes.

The billionaire cult is slowly dismantling itself. I came to adulthood in the early 2000s and I remember the presumption basically being that they must be very smart because they're very rich and if they're very smart about the thing that made them very rich then they must be very smart about everything else as well. There are cases where that has borne out. It's hard to argue that Bill Gates and Jeff Bezos aren't shrewd businesspeople who know how to use the levers of power to get what they want. But as a counterargument against that is Elon Musk, supposedly based on the mythos of the capitalist meritocracy the greatest among us (because, if not, how could he have become the richest?) who has revealed himself to be cruel, petty, awkward, desperate and has very publicly mismanaged several companies to the point of being sued by shareholders who've found his behavior to be so detrimental to the value of their holdings that it's inseparable from malice. A lot of people are realizing that it's a crap shoot. Being smart is certainly an advantage, but it's one of many and being rich or having access to powerful people seem to be just as influential.

One of the most revealing things about Musk came from Walter Isaacson's biography on him. According to the book, Musk once joined a poker game at a table full of card sharps, odds savants and the kind of people you expect would play a lot of poker and would also eat alive anyone who wasn't on their level. He bulldozed them. His strategy? Bet everything he has on every hand and, when he loses, just buy more chips. Isaacson seems to think this proves Musk to be an outside-the-box-thinking risk-taker but there's another, less generous interpretation: capitalism tends to elevate those who have enough resources that they can get their asses kicked 10 times and still come back for an 11th, but the odds are against you if you're playing with all you have no matter how gifted a player you actually are.

There is certainly a usefulness in separating government spending and private spending in our economic health measures. For one, measures like GDP are often used to evaluate the confidence and the general well-being of our economy. High Government spending tend to indicate the opposite, as Keynesian economics would mandate. More so, it invite manupulation of those measures by politicians, who can increase deficits to boost their "success". When it comes to spending like Education, those should be fairly constant relative to the population, in a developed country. We also have other mechanics to discuss their health status since they are largely public funded and subject to political debate. Perhaps a good measure would be the GDP minus public deficit minus credit card debt increase.

The whole point of using economic metrics like GDP is that they are NOT politicized. You can argue to what extent that succeeded. Probably not 100%.

But your suggestion is to increase politicization of GDP: change the figure to push a certain view on economic activity, as opposed to what the theory says, what's practical, and what actually happens in real life (even if the government pays a group of people to dig a hole, and another group to fill the hole back up, that's still economic activity and should be counted).

That's moving things entirely in the wrong direction.

No! The problem with GDP isn't that it's a score, it's that it's a BAD score. We know whats wrong with it. It's fixable, it doesn't ignore very many things! The main issues are totally tractable. In addition to ignoring utility:

1) GDP doesn't account for changes in net wealth.

If I take out a loan to buy candy, GDP goes up. After I eat the candy, the loan remains. I'm financially worse off. GDP still went up! Economy is doing well!

GDP also ignores depreciation. Machinery/infrastructure decay doesn't affect GDP at all.

2) GDP doesn't account for externalities or zero-cost innovation/value.

If I pollute the water supply to make an additional $10, GDP went up.

The inverse is also true. If I make Wikipedia freely available, the value provided to humanity does not affect GDP.

GDP is a bad metric, but it's not worthless. It's a bad metric if you only use it in a vacuum, if you are knowledgeable and combine it with several others you would be more effective into improving the society at large.

Not at all, even if there was snark intended I think its a fair question.

I resisted ranting about it (I hope you'll indulge me now), but in general I don't much like the economics commentariat. As best I can tell, "respectability" seems to mean something like "modal economic views + left of center politics." There are of course some exceptions, e.g. occasionally the economist or WSJ, but it leads to some notable blind spots.

For example, Switzerland experienced mild deflation in a good economy 2012-2017, but it wasn't until 2023 or so that articles started coming out that questioned where the 2% inflation target came from [0] and whether deflation could ever be a good thing [1]. This was despite respectable research from at least 2004 that explored the possibility of "good" deflation [2].

Tim, like many in the commentariat, was writing about inflation in 2019 [3]. The title of this essay is "Why inflation is good for us," and discusses the merits of inflation without any real discussion of cases where deflation could be good. At the end, he even raises the idea of a 4% rate target, which is a tad funny knowing the political mood on inflation 2021-24.

My point, really, is that I suspect I know most of his opinions without reading much of his work. He's hardly unique in that regard, but it bothers me. When looking for interesting opinions I'd probably look elsewhere.

This is true, but it used to measure (or at least try to account for) decay in private companies. Changes in accounting techniques make this a challenge nowadays (especially since our beloved MBAs invented 'future accounting', where expected ROI is added to the value of machinery in the books, truly a genius move by true sociopaths)

No, the "G" in GDP stands for "Gross," which means before depreciation. Depreciation has long been estimated in NIPAs, but that's a separate slate of measures.

> (especially since our beloved MBAs invented 'future accounting', where expected ROI is added to the value of machinery in the books, truly a genius move by true sociopaths)

This isn't true either. You're describing valuation models, e.g. DCF, but these aren't used for accounting. GAAP doesn't have a concept of adding ROI to asset value.

It is very true that games are played with depreciation. For example, you're allowed to depreciate some assets like real estate even if they INCREASE in value over time. All of that depreciation is tax-deductible.

While I can't say that Musk is right, I also can't say he is completely wrong here.

The private sector can also spend on dumb and inefficient things and we are fine in counting it in the GDP metric, the difference between private sector and the government is the source of revenue. The private sector has to produce something for the economy before spending (it may be done indirectly through debt, but it's not important here), while the latter forces the economy to share it's productive capacity (using violence if necessary) while not producing anything itself (well, technically it does, but it's usually a tiny amount of the total revenue). It's still fine, since it's just a form of re-distribution from one private entities to others. It can be grossly inefficient, but so can be the private spending.

The problem is when a significant portion of the government revenue is fueled by debt which can not be paid by the future economy growth. The government quickly engineers negative real interest rates either by forcing commercial banks and pension funds to buy it with regulations, or by outright money printing, which is easy to do in a fiat system. Such debt-fueled GDP growth is not a sign of strength, but instead a sign of weakness, and ideally it should be heavily discounted.

I am not sure against what you argue exactly. My point is that if we use GDP as a metric of economy strength, then it's easy for the government to cheat it by fueling it's spending by printed money (ah, sorry, the reputable economist use the "quantitative easing" euphemism instead) or by unfair debt issuing practices (like forcing banks, pension funds, or even people directly to buy government bonds), then it results in a short term "sugar rush" GDP growth, while consequences are kicked down the road. In the US case we also have an additional masking factor in the form of having control over the world's reserve currency, which significantly dampens the usual inflation reaction.

So if we want a better metric, we should somehow discount this factor. Obviously, simply removing the government spending is too simplistic (or you can call it less charitably as "dumb").

Ok, here's another neat trick about the GDP. We do not measure growth of the GDP in nominal values, but real values, aka, we adjust for inflation (yes, this is the _only_ case where you can actually "adjust for inflation" and will be valid). We use something called deflator which allows us to ignore the variances of value in the currency due changes in monetary policy.

So, the government can "print money" (that's not how it works), which would cause inflation (aka, the currency loses value), so the effect on the real GDP is muted. There's another thing that happens when the government goes into a spending spree which is "crowding out", basically the government buys what households and business would have bought and therefore they don't buy anymore, so the effect of the GDP is muted. There are many other things that happen also due such actions that would actually make the GDP to contract!

Anyways, reckless fiscal policy alone doesn't "manipulate the GPD values". Economies do not work in a vacuum. There's tons of interactions that are not explained because it's too complex to do so without the previous knowledge, to do so in a short amount of hours would be very dangerous because you would think you understand things that you really don't understand. Take a course of macroeconomics, of about 100 hours, and it would only be the start. Then industrial economics, economic policy, taxation, international economics, monetary policy, monetary economics, you get it?

>we adjust for inflation

Using a very debatable inflation metric (e.g. should deflationary technological advancements in electronics manufacturing boost the "real GDP" metric?), which is quite muted (even with the post-COVID spike!) on top of that because of the "exorbitant privilege".

>that's not how it works

Suuuure. The recent examples of collusion between banks, the government, and the central bank to quickly increase amount of base money is not outright "money printing", just benign "quantitative easing", nothing to see here.

>crowding out

This works only when government engages in "fair" and competitive debt issuance. But we see a different picture, government bonds are counted as bank reserves and even worse banks do not even have to apply the mark-to-market accounting rules for them in some cases. And everyone knows that the Fed immediately will ride to the rescue on the first sign of trouble in the bond market as was done during not-QE.

>reckless fiscal policy alone doesn't "manipulate the GPD values"

Alone? No. But it certainly boosts GDP (both real and nominal) in the near term and makes the economy look better than it really is. It's the same story as in China where they had massive "infrastructure investments" to artificially stimulate the economy and make GDP numbers look good. We can see in the real time how it unravels.

The only valid point of concern is government self-spending. Maybe we can look at GDP and GDP excl govt spending as 2 separate metrics, each has its own merits.

A relative of mine is working for my country's government for a very long time as a high level economist and leading a government department. One thing that is happening is lots of made-up jobs with made-up work; this is just to keep unemployment low, but most of the money (>60%) return directly to the government as taxes. It artificially increase the GDP. This relative has several hundred of people in the organization that they run, about half are politically appointed (as in "every new minister or state secretary is employing dozens of their friends and relatives") and about 3/4 are not doing any job that results in a positive outcome. Most of the work is paper-pushing "analysis and reporting" that are have no real impact on anything, but are still hired as the number of positions is imposed from very top and hiring is also "influenced" from the top. So what happens with the GDP? It is increasing artificially and it is meaningless in this context.

GDP = buying/selling things and investment. Government spending is almost always buying something. How could you extract this from GDP?

Elon is saying government spending should not be included in GDP. In reality GDP is what it is; find a new metric to use.

the quality of using GDP as a metric is low because of this. Also why GDP growth matters so much. Recessions are defined as negative GDP growth by 2 quarters. So government can deficit spend to hide a recession, that's the problem.

What you have to look at isnt GDP at all. find a new metric to use to determine recession. Here's mine.

Real GDP minus government deficit(all levels of government combined) per capita.

When you look at this metric. Canada, Germany, UK, France, Italy, Japan, spain, and estonia are in hidden recessions. Also why they all pretty much need to be negative bank rates and high inflation right now. Obviously this is a WW2 consequences that were put off until now.

Other ways to see the problem is 2030 worker shortage or the inverted population pyramids.

Russia has been selling large amounts of long-term sovereign bonds, going into debt, at an annualized interest rate in the mid 20%'s (!). While under a looming demographic crisis featuring very large numbers of elderly pensioners being supported per young worker. A non-negligible fraction of those young workers are fleeing the country or dying in Ukraine, which further deepens demographic issues.

This is destabilizing for a variety of reasons. It's a bet on future growth that does not appear evident. It's also effectively a burden placed on the other oligarchs behind Putin, who would love to control a large chunk of a functional economy rather than controlling a large chunk of a banana republic undergoing stagflation and being heavily taxed for the privilege.

wow, that is kinda dumb.

Governments can and do target GDP with their spending, with predictable results. The classic example is "ghost cities" in China. They have ghost cities nobody lives in, ghost roads nobody drives on, and ghost bullet trains that go nowhere useful. All because regional governors are expected, one way or the other, to match GDP targets for their regions.

Goodhart's law applies here. "Any observed statistical regularity will tend to collapse once pressure is placed upon it for control purposes." or "When a measure becomes a target, it ceases to be a good measure."

GDP is subject to manipulation when it becomes a target. So is lots of other things like "Consumer Price Index", which nowadays doesn't index a whole lot other then what the goverment's target is for inflation (and yes, the Federal Reserve actually counts as part of the "government" here).

Which means that GDP, like the CPI, is not particularly useful measurement anymore.

Most of the "Ghost Cities" that you read about ten years ago are now normal cities full of people. The Chinese innovation was building the cities before you moved people there, "opening" the city empty and then watching it slowly fill up with residential and commercial over a decade or two. This was always the plan. In the US, our current plan for cities is "Don't build them at all". In the US media we obsessively create headlines over Those Wacky Chinese And Their Weird Things, but we come up well short in this particular comparison.

For historical finance-culture reasons (they're reflexive savers, and there aren't many other investments allowed), China does have a lot of real estate investment relative to population, even considering their rapid urbanization, and not all of it is looking to be sustainable; In retrospect there's been a bit of a bubble. But >90% of it? There are hundreds of third/fourth-tier cities housing hundreds of millions of people that might have drawn fire originally under "Ghost City" theory.

In a worst-case scenario, what Chinese people get instead of a return on their nest egg investment is inexpensive houses/apartments with more living space, and maybe the option to support themselves without a DINK family.

Yes. Let's compare SwissLife, a private healthcare insurance, to French 'securité sociale' healthcare bit.

For every 100€ put in french national healthcare, 89 to 93 (depending on the year) are spent on healthcare. The rest is used for distribution and administrative tasks (and during a short time, debt repayment).

What do you think SwissLife give it's insured back for ever 100€ they are paid? Between 12 an 15% are administrative costs (they have more expensive lawyers and contest more claims), 2% R&D (??for some reason, probably to claim tax rebates), and between 5 and 12% are dividends. So between 81 and 71 euros are given back. Do that seem more efficient?

But that won't last, each time private companies compete with public one, the EU commission had to create new rules, like ARENH for electricity, or worse, the separation between SNCF, SNCF reseau, SNCF fret/geodis to prevent economies of scale and local optimisation (that killed small train stations and most french fret). Now that SNCF fret managed to come back (under a new name) and outcompete everyone, again (mostly because train fret died), they just broke it again for spurious reasons. Liberalist fuckers just don't want exception to their rules, and since they can't economically bully state companies like they bullied Lip and probably any worker cooperative that became too big or too well-known, they use their political weight to send them to the ground instead.

Define "worth it" macroeconomically. There is no "value" idea at scale with a meaning separate from "money". Every transaction happens, definitionally, because the two parties think it's "worth it".

> When the government spends your money, you don't get to decide whether a particular transaction is good value.

And here's the root. That is an argument from principles of libertarian morality, not economics. It's fine if you want to claim that it's immoral for the government to tax and spend your hard earned assets. I just won't engage, because that's tiresome.

It's not fine to claim that the government stealing and spending your Lockian Sacred Property is "not productive" in a discussion about economics, because that is a word with meaning in the field and you're using it wrong.

(Edit: as stated, I'm not going to engage in a discussion on libertarianism in an economics thread. I'm merely pointing out that you have the economics wrong.)

I made no claim about the morality of taxation and government spending.

I'm merely observing that, when we attempt to measure economic activity via GDP, we run into a fundamental valuation problem with the government component (G). Private consumption (C) and investment (I) are valued using market prices derived from voluntary exchanges. These prices, imperfect as they are, provide at least some signal about the perceived value placed on those goods and services by willing participants.

Government spending, for the most part, lacks this direct market-based valuation mechanism derived from voluntary choice.

Because there are usually no market prices for government outputs (like defense, regulatory agencies, or infrastructure projects before user fees), GDP accounting defaults to valuing them at cost. So, if the government spends $1 billion, it adds $1 billion to the 'G' component of GDP. This is convenient from an accounting perspective, but it doesn't actually tell us whether that $1 billion expenditure generated $1 billion (or more, or perhaps much less) in genuine economic value or utility *as perceived by the citizens who ultimately fund it*.

Therefore, questioning whether government spending represents "good value" or is truly "productive" in the same sense as market activity is relevant if you're trying to get a useful measure. (This is true irrespective of your opinion about the morality of taxation.)

It's a well-known limitation in how we construct and interpret GDP figures.
