It gets real tough to hold to your beliefs when it hits your pocket book. I'm getting some work done on the house and have been collecting quotes. Here is a real example:

Non-citizens quotes for a job $800, and $1150.
US-citizen quote: $1850.

I didn't even take quotes from another half-dozen other Mexicans. I could only find one American in my area listed on Craig's List (brick work).

Dang it hurts; but I'm going with the American even at twice the price. I told the guy the situation and he says he deals with it every day. The Mexicans bid real low. And after 17 years it's getting harder and harder to get jobs. He agreed to take $200 off and do it for $1650. And did I mention he speaks perfect English?
