I know or have known a lot of illegals (they somehow get licensed as asbestos workers in spite of their status). They all have been loyal to Mexico, and would have gone back on weekends if given the choice. I live in deep south TX. One guy told me how great Mexico is. I asked why he was here. “Oh, I can’t make a living there”.
The local asbestos enforcement inspector was asked how these illegals were able to qualify for licenses (several crews on licensed workers and supervisors were picked up from jobs and deported). He laughed and stated if not for the illegals (who are nearly the only ones who will do the work) there would be no asbestos abatement crews.
One of the oil companies I worked for employed three or four young men to help clean rail tank car interiors. That had to be the most disagreeable, ugly work imaginable. The cleaning process used a chemical to remove most of the baked on asphalt, then the guys would get inside with power grinders to get the stuck on chunks.
The company sent 75 percent of their pay to families in Oaxaca.
