Yes. I know many a wallboarder that lost their jobs/businesses because of illegals that used stolen SSN’s and took these jobs. Roofers, construction workers, mechanics, cooks, (some restaurants will not even interview you if you are caucasion). So, yes, they take jobs away from citizens and lower wages in some/most industies.
I never said they didn’t take any jobs. And the economy is different in different times and in different areas.
