In fact, as has been noted before in other threads, anybody truly interested in the welfare of American workers, and not just trying to use this idea as a smokescreen for his own prejudice would, if he thought clearly about the problem, be in favor of a path to citizenship for illegal aliens.    It is obvious why:    if illegal immigrants are driving down wages for legal workers, the reason is that employers know they can pay below minimum wage, and the workers dare not complain for fear of deportation.   If all illegals were made legal, they could blow the whistle on any employer paying below minimum wage, or otherwise mistreating them.

It is also clear that the alleged concern with overpopulation, particularly as it affects the environment, is a facade for prejudice. Much current environmental degradation in the border area is caused by illegal immigration and by the current fence, planned to be extended. Both of these problems would be addressed by making illegal immigration legal immigration. Also it is a historical truism that first generation immigrants often have big families--but with education and more prosperity immigrants realize their quality of life is better with smaller families. And succeeding generations take this to heart. So extrapolation of large immigrant families into the future is not justified.
