The majority of the country hasn't shifted nearly as much, however, so there is a huge echo chamber in the media.
The absolute state of modern media.
Businesses, knowingly hiring illegal labor for cut-rate wages that they couldn't pay Americans, and illegal immigrants getting illegally paid under the table without taxes... is described as "relying on foreign help".
