Are you saying that the American people have already lost control, and that it is too late to stop this overpopulation.
You seem OK with the world of foreigners making what ever they choose of our country, I’m not, I think that we filled up a long time ago.
The root cause of the majority of the problems in the United States today is an "American people" that for several generations now has been far too willing to hand over the reins to a central government.
And believe me, that problem has been going on since before the recent waves of legal immigration.
and that it is too late to stop this overpopulation.
The United States is far from "overpopulated" (as you claim). Just drive around in the countryside of practically any State in the Union.

Dude, that IS the history of this Republic. That is exactly what's been going on for about four hundred years, five hundred if you count the former Spanish possessions that are now within the United States proper. Everyone living within the territorial bounds of the United States today--including YOU--descends from someone who immigrated here, whether lawfully or not.
