When parents have college savings accounts for their kids, their kids show higher social and cognitive performance.

In the U.S., I think there is an ideology of not telling kids what to do. Nobody to tell you who to marry, not tell you what job to pick. You're your own person. You have the freedom to choose, including the freedom to fail in magnificent ways. And I think that's the big difference. In other countries there is basically a social norm about saving that is passed from generation to generation. In the U.S. there isn't.

Ownership is not limited to material things. It can also apply to points of view. Once we take ownership of an idea - whether it’s about politics or sports - what do we do? We love it perhaps more than we should. We prize it more than it is worth. And most frequently, we have trouble letting go of it because we can’t stand the idea of its loss. What are we left with then? An ideology - rigid and unyielding.

When you're in pain, tomorrow doesn't exist - just the pain - and the only thing that you want in the world is for it to go away.

If you want to spend more money in restaurants, use credit cards more than cash. If you want to spend less, use cash more than credit cards. But in general, we can think about how to use the pain of paying and how much of it do we want. And I think we have like a range. Credit cards have very little pain of paying, debit cards have a little bit more because you feel like today, at least it is coming out of your checking account, and cash has much more.

We need to believe that we're good people, and we'll do just about anything to maintain that perception.

that when given the opportunity, many honest people will cheat.
