My business puts me on Farms ALL OVER the Lower 48 United States, Mexico, and Puerto Rico, every day. It is true EVERYWHERE. And New Mexico is one of the worst offenders. Poor land quality and lack of water in the desert Southwest change the outdoor aspect of the business — and that is all. In any location where labor is intensive, illegals are used.
I’m not saying the farmers here don’t hire illegals- I do know farmers and ranchers that do NOT ever hire illegals though and somehow they make it work.
