Red states that lose their farm workers are going to be dependent on blue states for food and that is NOT a position that works out well.

a) How so? We're part of the same union. Do you think they're going to imposes tariffs?

b) Maybe the reason Americans don't work the fields is because the wages are artificially low and suppressed. It's not like "farmers" (corporations) are just going to give up farming altogether and leave these industries. They'll have to take a paycut and stop exploiting workers. The free ride is over.
