"Labor is already tight with unemployment below average and shortages existing in both geographical and industrial sectors."
BS! There are millions of Americans looking for jobs currently being stolen by third world illegal aliens. I know many of them. Where do you live on the Moon?
Do you really know many people who can't compete in the labor market with illegal aliens? Do they speak English, have a drivers' license, don't have any arrest warrants out for them? Why do employers prefer illegals over them? That's strange.
I know one guy who can't keep a job very long who's always complaining about Mexicans, but we just figure he'd rather sit around drinking beer all day while his wife works at Hooters. When rent and truck notes are due she takes on some extra work.
I'd prefer to hire anything before I'd hire him.
