The graph above is from this post at Gallup:
WASHINGTON, D.C. — Significantly more U.S. adults than a year ago, 55% versus 41%, would like to see immigration to the U.S. decreased. This is the first time since 2005 that a majority of Americans have wanted there to be less immigration, and today’s figure is the largest percentage holding that view since a 58% reading in 2001. The record high was 65%, recorded in 1993 and 1995.
The last time the percentage of foreign-born in the United States was as high as it is now we, basically, slammed the door on immigration for forty years. I have been warning about this for some time.
I, personally, would prefer that we were able to accept more people who are genuinely in need of asylum and that we accept a certain number of highly-trained individuals to work in the United States. I would prefer that over shutting the door. Farther down in the same post, there is a finding that the percentage of people who support mass deportations is increasing.
