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.
"Do you really know many people who can't compete in the labor market with illegal aliens?"
The above question is irrelevant as illegal aliens are not entitled to be in our country in the first place. But since you asked - although I had already responded to this query in an unambigous declarative statement - YES.
"Do they speak English, have a drivers' license, don't have any arrest warrants out for them?"
Except for the last part, the rest is trivial and not relevant. My father, who is an American born citizen, never had a driver's license, and yet he worked his whole life w/o it.
"Why do employers prefer illegals over them?"
Simple: low wages, cowardice, betrayal, closed-minded, and visionless.
"That's strange."
I doubt it's strange to you. If it is, then you must be a very naive person.
Just as a percentage of Americans are losers, a percentage of illegal aliens are losers too.
