My comment is not based on crops but there are a lot of people that get temporary visas from Central America for these farming jobs in the US. There also more people then you think here that will do this work. Half of my family has picked seasonal fruit in Florida. My comment was on corporations that manufacture stuff. Example there is a local business where I live that use to manufacture grills here in town. In the 90s they shipped those jobs over seas. They now send materials to china to manufacture parts then send them to Mexico to assemble the back to the US to sale. That shipping cost a fair amount but the business made a little bit of extra profit still because of the labor cost. The tariffs now in place makes it cheaper for them to manufacture it here now… The Corporate greed is astounding
