Immigration Arguments

I was listening to one of the proponents of amnesty for illegal immigrants the other day, and something struck me about his arguments.

First, they were strictly economic in nature. I suppose I shouldn't be surprised to hear that from the left, given the essentially complete takeover of the left by socialist thinking, but it still seems odd.
Secondly, they seemed eerily reminiscent of arguments not heard in this country since the mid 1800s. The whole justification seemed to be essentially the same as the justification for keeping slavery in the soon-to-be Confederacy. It boiled down to this: we can't find Americans willing to do these jobs at these wages, so don't take our Mexicans away. Given the amazing blinders as to the true costs of illegals with which the left tends to view this situation, I suppose it's far from surprising that they don't see that paying a wage at which an American would do the job would actually cost us all less than paying the outrageously low wages and letting the taxpayers pick up all the extras.

I have absolutely no compassion for businesses which are based knowingly on breaking the law. Neither should you.
