Well, I truly don't know, so I won't argue the point. But I will say, if that is true, then why not educate our people. Please don't tell me that the only reason they are hired is because they are better workers.
So because these are better workers, we just scuttle the American people, we just forget about the generations to come.
But once again, just like the illegal aliens, the cost to the corporation who is profiting from them might be smaller - but the overall cost to the American taxpayers and America as a whole is huge.
