You’re right they’re not cheap labor. I live in a small town in one of the poorest counties in Pennsylvania. You shop in the local grocery stores and you see recent immigrants in their native garb or jabbering away in some foreign language. They make their purchases and go out to the parking lot where they get into top of the line, brand new, Mercedes, BMWs, or some other $50,000-100,000+ status symbol. Meanwhile, locals, whose families have lived here for generations, drive rusted pickup trucks or other wrecks and hunt or fish to feed their families some protein. Opioid abuse is rampant. Some of these Americans live in little more than shacks out in the woods. It isn’t because they’re lazy; in many instances their work in the coal mines and steel mills is gone thanks to the policies of the Republican and Democrat administrations, particularly Obama’s. They’ve been forgotten as the government promotes the interests of big business and immigrant rights organizations. The American dream is now for the immigrants driving the big, expensive cars who work in high tech in Pittsburgh and live in the country.
In many cases you are correct; HOWEVER, in all cases they're not American labor. In other words they are not culturally Americans and as such they are much more 'flexible' to not defend God-given rights and to assist Leftist ideologues in "sticking it to" Americans. I would suggest that many of these foreigners are conspirators in much of the censorship on Social Media as well as being willing or unwilling useful idiots for foreign and domestic activists that are or represent enemies of America...
