US farm labor is heavily undocumented-immigrant-dependent. Estimates vary, but undocumented workers make up something like 25–50% of the agricultural workforce, especially in crop production. (In specialty crops this percentage can be much higher, but those won't matter for "starvation").

Remove all of them, fruit and veg production falls 15–20%, dairy & animal products 10-20%. Calorie production has higher variation in estimates, I've seen anything from 10% reduction to 40% reduction, but the whole "undocumented" thing makes it harder to be sure.

In any event, you get double-digit percentage price hikes, and a lot of Americans are already struggling with the current prices.

You may call your country your home colloquially, but if you can't tell the difference, if you really genuinely can't differentiate, then you must accept that everyone who welcomes them into their country has already welcomed them into their home.

To your specific list, this sarcasm: sure, because there's no such thing as local sociopaths, I don't live next to a forest with wild boar that I've witnessed breaking into neighbour's gardens, I'm fully aware of local laws about professional cooking, and also I'm funded sufficiently to be a charity.

And for that last point, I will remind you that you've already used the word "illegal workers". They work. They pay for themselves.
