IMO the minimum salary should be $0 and Americans should be free to hire whoever they want, without paying a fee and asking permission from the government. Non-citizens should be subject to the same minimum wage and workplace regulations as everywhere else. Whoever wants to come to America should be able to freely come, treated the same as anyone else.

But that would be a free market that respected human rights, and Americans don't want that! Equality? Freedom? That's just marketing!
