That is the only cultural assimilation which absolutely must happen as soon as possible (for the immigrants’ sake if nothing more). As far as I can tell our current crop of immigrants are no different than prior generations (if anything they are probably making faster progress towards assimilation because of modern technology). Old style communities in the Midwest could stay insular for generations.

Demonizing these people makes absolutely no sense. An argument could be made that the government’s first priority is gainful employment for U.S. citizens (immigration has always created a labor/management tension as companies look to reduce their labor costs as far as possible). Striking a balance that strengthens the U.S. while not being inhumane seems to make the most sense.
