Spend less than you make; always be saving something. Put it into a tax-deferred account. Over time, it will begin to amount to something. This is such a no-brainer.

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.

It takes character to sit there with all that cash and do nothing. I didn't get to where I am by going after mediocre opportunities.

I think the foundation at Berkshire [Buffett's stake in Berkshirewill pass to the Buffett Foundation upon his death] will be a plus because there will be a continuation of the culture. We'd still take in fine businesses run by people who love them.

I think the idea that the hedge fund manager gets lower taxes than the taxi driver or the physics professor is insane. The legislators who leave that policy in place are derelict in their duties to be rational and fair. There are plenty of them in both political parties. It's totally outrageous.

I'm very pleased when the smartest people come [to the U.S.] and almost never pleased when the very bottom of the mental barrel comes in.

I think you'll make more money in the end with good ethics than bad. Even though there are some people who do very well, like Marc Rich-who plainly has never had any decent ethics, or seldom anyway. But in the end, Warren Buffett has done better than Marc Rich-in money-not just in reputation.
