Except they will pay more for lower quality work.
If you are a loser living in a rural trailer park, you simply don't have much of a work ethic. Immigrants will work their asses off, trying to better themselves. So pay more money for people who don't work nearly as hard.
That's a great business plan. You should try to implement that.
I'll give you a real life example. I worked for a company that hired a bunch of "contractors" to do assembly. We kind of knew they were undocumented, but they worked hard and if the staffing agency said they were good, we had no issue.
Well, low and behold, when they got bought out by a bigger company, the edict came down that you had to prove they were Americans. The Mexicans all left, and they found these white meth-heads who were not only not nearly as effective, but really scared the customer service ladies. When they got paid, they'd go off and get high and not show up the next week, and they sent a whole new batch of methheads.
But they were white and American, Dammit!!!
