Artificially created? You seem to want open borders with no government control of who comes here.
Not at all. But we should allow in whatever number that it takes to fill the jobs. Our unemployment rate is at nearly an all-time low, particularly in the border states, so there is no rational to keep people out. Attempting to keep people out who have a proven ability to get and keep jobs is the black market that our broken laws have created.
These people are going to be here, whether your or J.D. Heyworth likes it or not. So we'd best deal with them by IDing them, teaching them english, and pushing them to assimilate. As long as they stay in the black market, that will not happen, as we have seen.
