"Open borders? [...] That's a right-wing proposal, which says essentially there is no United States. [...] 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. You know what youth unemployment is in the United States of America today? If you're a white high school graduate, it's 33 percent, Hispanic 36 percent, African American 51 percent. You think we should open the borders and bring in a lot of low-wage workers, or do you think maybe we should try to get jobs for those kids? I think from a moral responsibility we've got to work with the rest of the industrialized world to address the problems of international poverty, but you don't do that by making people in this country even poorer."
