The market will fill the voids. Nodoby needs to resort to breaking the law, under ANY circumstances.
I am building a house right now. If an illegal comes on my property, I'm telling the contractor to remove him. So far, we have the walls framed, and not a single illegal has been here yet. Yep, only Americans are building my house.
I also own a business. I could hire Mexicans at a fraction of what I pay my American employees, but I refuse to. Guess what- we're doing fine, and God blesses us with excellent contracts.
To hear people like you talk, it's as if Americans aren't capable of doing this. PLease!
The market can't gill the void, that's the problem. People are only having 1 or 2 kids and sending them to college. Our population is aging. There are simply too few Americans who want to are are even able to do physical jobs. The idea that there are 10 millions of able body Americans willing to do physical work is a total myth. The people to do these jobs simply do not exist at any price.
