I will say this one thing. I do not know what will happen in the next few years, but once Donal Trump starts trying to deport millions of people, there will be massive unrest. Not only do immigrants support the farming industry but also do work that most Americans would not do regardless of the jobs being there or not. Would you go out and work hard under the sun all day long for 8 dollars an hour? Chances are you would rather be in an AC office or store then to go do hard labor for such low prices.
Not to mention all the Human Rights organizations that would start putting pressure, boycotting and who knows what else.
Trump may be the President but he still does not have the majority of public support. He lost the popular vote lets keep that in mind.
