Perhaps a tad off topic. I might mention that many family farms would no longer be able to operate without the help of migrant workers who are often undocumented.

People in the southwest will have this issue forever more. Those states were owned by Mexico, even if we stole them fair and square. Build a 20 ft. high wall, they will build a 22 ft. ladder. Good luck stopping those native to the land. Course, our country has pretty much eliminanted native peoples. Maybe the "illegals" are next in the genocide line.
