Excellent point. Myopia from the top of the mountain is a disease that offers no treatment. Unless Bush and others afflicted go broke and have to work their way through a master's program while waiting tables. Naw-- Won't happen.
I'm sorry but those will be taken up by illegals "doing jobs Americans won't do."
In my area, we have Bulgarians, Romanians, and other eastern europeans doing skilled construction work. Im not sure why, but construction companies seem to prefer aliens, maybe because they are bending rules and codes, and maybe union regulations, and the eastern europeans wont complain, dont care, and wont report it. But I do agree with your point, that foriegners over here will take over construction jobs. With asians flooding the medical profession, Im not sure what jobs will be left for american citizens.
