A big Nebraska meat packer lost lots of workers after an ICE raid. Guess what happened next.
Remember this story out of Omaha where the feds used E-verify to track down more than 100 illegal aliens using fake IDs? And that those illegals allegedly pulled box cutters on ICE agents?
I wouldn't even call construction uneducated - it certainly isn't for the unmotivated and usually there are opportunities to learn new skills if you look for them. A carpenter is an educated tradesman. The mexican contractors ofte only learn how to do one job, and poorly at that, with all the premade house kits going up, but actual builders have skills.
Whenever they tell you that we need unlimited third world migrants to fill construction jobs, just think about all the small towns that still have beautiful brick buildings standing 100+ years after they were built versus the crappy plywood suburban houses we have now.
