Take Our Jobs!
Common sense: Depressed wages follow free labor:
Sure, they still require labor, but the workers would be fewer, and more productive, and thus better paid, turning what is now a primitive, atavistic work environment featuring exploitation and injury into something a little more civilized. No one dreams of a career collecting trash, either, but with high pay and automatic can-dumpers, there are plenty of (native-born) takers.
Good to see the tired argument — that nobody would take the jobs illegal immigrants do — being put to bed.
