The bigger question is WHY do our politicians think we welcome this invasion? Who convinced them that these are "hard-working people who only take the jobs that Americans won't do?" Grrrrr! That is such a farce!
My own little community here in TN seems to be encouraging illegals. I just discovered that La-Z-Boy, once an icon of community standards who would only hire high-school grads, is now hiring Mexicans who can't speak English (I don't know how to find out if they're illegals or not, but I'll report them in a heartbeat if I can find a way). The wages are now lower at the plant, a direct result of third-world competition.
