On Immigration: Open borders for guest workers pushes down U.S. worker wages

A: Open borders? No, that's a Koch brothers proposal.

Q: Really?

A: Of course. That's a right- wing proposal, which says essentially there is no United States.

Q: But it would make a lot of global poor richer, wouldn't it?

A: It would make everybody in America poorer --you're doing away with the concept of a nation state, and I don't think there's any country in the world that believes in that. If you believe in a country called the United States or any other country, you have an obligation to do everything we can to help poor people. What right-wing people in this country would love is an open-border policy. Bring in all kinds of people, work for $2 or $3 an hour, that would be great for them. I don't believe in that. I think we have to raise wages in this country, I think we have to do everything we can to create millions of jobs.
