BUMP!
I work in a field where I see many skilled trades being filled by these people. Skilled trades mind you......and it makes me more angry when I hear the foreman speaking Spanish to them.
I think option two is the most feasible......well, maybe most effective. Don't count on it though. Democrats like cheap voters, and Republicans like cheap labor.
Which means your average American tradesman is getting screwed (pardon my English......or is that Ingles).
Fortunately, my boss is an extremely patriotic type who doesn't stoop to save-a-bucko-hire-an-illegal-Mexican.
