Opportunity cost is a huge filter in life. If you've got two suitors who are really eager to have you and one is way the hell better than the other, you do not have to spend much time with the other. And that's the way we filter out buying opportunities.

Berkshire has the lowest turnover of any major company in the U.S.The Walton family owns more of Wal-Mart than Buffett owns of Berkshire, so it isn't because of large holdings. It's because we have a really unusual shareholder body that thinks of itself as owners and not holders of little pieces of paper.

I think that if you have a single payer system and an opt-out for people who want to pay more [for better service, etc.], I think it would be better - and I think we'll eventually get there. It wouldn't be better at the top - [our current system] is the best in the world at the top. But the waste in the present system is awesome and we do get some very perverse incentives.

In investment management today, everybody wants not only to win, but to have a yearly outcome path that never diverges very much from a standard path except on the upside. Well, that is a very artificial, crazy construct. That's the equivalent in investment management to the custom of binding the feet of Chinese women
