Over the long term, the eclipse rate of great civilizations being overtaken is 100%. So you know how it's going to end. (Laughter) I'm more optimistic about the staying power of what's good in this country. But just because you have a wonderful spouse doesn't mean you should treat her badly. You have the feeling that some of the old virtues [that made this country great] are lessening. But there's so much good and so much strength left that I would not expect this country to suddenly founder.

There are a lot of things in life way more important than money. All that said, some people do get confused. I play golf with a man who says, " What good is health? You can't buy money with it."

A banker who is allowed to borrow money at X and loan it out at X plus Y will just go crazy and do too much of it if the civilization doesn't have rules that prevent it.

We've had the most massive creation of wealth for people a lot younger than those who formerly got wealth in the history of the world. The world is full of young people who really want to get rich, and when I left school nobody thought it was a reasonable possibility.

I don't want to sell credit to people who are going to hurt themselves with it. You should only sell products that are good for the people who use them. Some disagree with this, but I know I'm right. That is to say, you're talking to a Republican who admires Elizabeth Warren.

I talked to one accountant, a very nice fellow who I would have been glad to have his family marry into mine. He said, "What these other accounting firms have done is very unethical. The [tax avoidance scheme] works best if it's not found out [by the IRS], so we only give it to our best clients, not the rest, so it's unlikely to be discovered. So my firm is better than the others." [Laughter] I'm not kidding. And he was a perfectly nice man. People just follow the crowd...Their mind just drifts off in a ghastly way.

We only want what success we can get despite encouraging others to share our general view about reality.
