Without regard to whether some place is wealthy or poor, everybody should have the chance at clean air and clean water.

Keep guns out of inner cities-but also problem of morality.

We have states. And we have cities. And we have counties. And we have the private sector. And - and so the country still works even when Washington's dysfunctional.

We think about the enormous costs of homelessness, or the enormous cost of HIV/AIDS, over the long term, as people visit emergency rooms, etc. The more we are investing in that ounce of prevention the better off we're going to be.

I am looking forward to getting out of the bubble. I am glad that I'm leaving this place at a relatively young age, at 55. So I have the opportunity for a second maybe even a third act in a way that I think would be tougher if I were, you know, the age of some presidents when they left.

We do not want to keep our troops in Afghanistan. We see no military - we seek no military bases there. It is agonizing for America to lose our young men and women. It is costly and politically difficult to continue this conflict. We would gladly bring every single one of our troops home if we could be confident that there were not violent extremists in Afghanistan and now Pakistan determined to kill as many Americans as they possibly can.

The trick is figuring out how do we structure government systems that pool resources, and hence facilitate some [wealth] redistribution, because I actually believe in redistribution, at least at a certain level, to make sure that everybody's got a shot.
