Oh, but they do, and it gets better.
Apply now, and Farmer Jeb will lease illegals living space cheap in trailers, sell them food too, which is a good thing, because they're not allowed to buy any from anywhere else. So not only are they hired at below minimum, they end up in debt to the taxpayer subsidized parasitic farmer whose family is too busy taking selfies at Walmart to work their own farms.
That's ok, because farmhands are sort of allowed to work overtime and with their underage kids too, who don't go to that free school for free stuff people yap about because if their parents don't make the day's quota, they don't get payed and heap on even more debt.
