First of all, many of those conditions can be improved. 12 hour days, minimal water, lack of bathroom, few breaks are imposed by employers trying to squeeze as much out of as few workers as possible. More people would be willing to do the job at maybe 25% cost to make conditions better. It my late thirties, I wouldn't do the job because I have better options, but when I was high school or college age I would have killed to do that job if it was paying $30 (in 2025 dollars)/hour. My dad literally did that type of job for a while in his younger years. Will that raise prices of food? Absolutely, but we're talking about going back to 1950s prices relative to wage, not about famine. ICE enforcement and immigration laws are also a choice. We can change those if we need to.
