I think the best thing that happened to the education system in New Orleans was Hurricane Katrina.

I just think we can't do enough of this [student exchanges]... And when you get young children traveling internationally, I think they come back different people. And you can't put a price tag - you can't put a value on that.

When schools truly become centers of the community, where you have extraordinary teachers, the best teachers, the best principals, great nonprofit partners coming in during the non-school hours to support and do enrichment activities, social services, then those students will beat the odds, will beat poverty, will beat violence in the community, will beat sometimes dysfunctional families, and be productive citizens long term. They will go to college.

If children are hungry, they need to be fed. It's hard to learn if your stomach is growling. We need to take that on. If students can't see the blackboard, need eyeglasses, we need to do that. If students need a social worker or counselor to work through the challenges they're facing at home in the community, we need to do that.

I believe that education is the civil rights issue of our generation. And if you care about promoting opportunity and reducing inequality, the classroom is the place to start. Great teaching is about so much more than education; it is a daily fight for social justice.

At a time when going to college has never been more important, it's never been more expensive, and our nation's families haven't been in this kind of financial duress since the great depression. And so what we have is just sort of a miraculous opportunity simply by stopping the subsidy to banks when we already have the risk of loans. We can plow those savings into our students. And we can make college dramatically more affordable, tens of billions of dollars over the next decade.

There was nothing more important I could do than be supportive as a dad.
