"We could provide you with copious data demonstrating the deleterious impact untrammeled immigration has on our economy and our society." I have seen at least one post stating that this guy is against ALL immigration.

Funny, but it appears that Do not specifically stated "untrammeled immigration" or "mass immigration" or 20 million influx of immigrants at one time having a disastrous effect, economically. The U.S. govt. has in place quotas to prevent a severe influx of immigration because that influx can and will cause an imbalance on our economy, local government, institutions of education, much as we are experiencing with the influx of illegals currently within our society.
