Farmers will have trouble finding workers willing to do the labor. I don't live in a farming town, but we have a stupid amount of Orange groves. Any person can walk off the street and instantly get a job picking oranges here. White people refuse to do this work, I know unemployed ones who I tell them "you can go pick oranges" they say "fuck that" It's 99% illegals, and they'll get deported if Trump has his way. Without the illegals I have no clue how these oranges will get picked. And I think to this day, Riverside's one of the biggest sources for Oranges in the entire US.
If the orange groves out here have to start paying white people $20 an hour to pick them, OJ will be out of most peoples price range.
