If I was homeless in LA, I still wouldn't work for 16 bucks an hour in the hot sun around dangerous chemicals with no benefits in the middle of nowhere.
In my country, you can work in a warehouse. You get job security, full health coverage, and 18 per hour. There are worker safety regulations that actually get followed, regular breaks, shade, and ppe provided if you're working with dangerous chemicals. You're not out in the sun all day. The US agricultural industry can't provide any of this. Why would anyone work for them if they weren't a poor immigrant planning to take their wages back to Mexico, where 16 is at least a living wage?
It is hard to determine which is needed more, as a home has costs, loosing a job leads usually loosing a home. I believe both are equally important, and this is kind of a snake biting its own tail problem, as without a home it is very hard to get a job. (Although I can imagine someone living in a car temporarily in mild weather conditions, it would be impossible to survive a winter that way here in Central Europe)
Hopefully this opportunity will help those in need.
This may help people get out of the hopeless situation, although I'm not sure how long an agricultural season is in California, here it is limited to at most 2/3 of the year, so this is a temporary solution at best.
