I'm slightly offended by the "doing jobs American's don't want to do". I think it might should read "doing the jobs Americans don't want to do for Third World Wages". I have no problem with people coming here to work. The part where it becomes an issue is when said work isn't enough to raise a family on, and the US Treasury has to pick up the slack for food, housing, and lots and lots of healthcare.
But there are groups of people who see voters. And they will toss aside their constituents to get re-elected. Term limits now.
