We like our current shareholders and don't want to entice anyone to become one. It would help current shareholders to hear our CEOs [of the Berkshireoperating subsidiaries], but we promised them they could spend 100% of their time on their business. We place no impediments on them running their businesses. Many have expressed to me how happy they are that they don't have to spend 25% of time on activities they didn't like.

Why should it be easy to do something that, if done well, two or three times, will make your family rich for life?

I believe that we are at or near the apex of a great civilization... In 50-100 years, if we're a poor third to some countries in Asia, I wouldn't be surprised. If I had to bet, the part of the world that will do best will be Asia.

Intelligent people make decisions based on opportunity costs.

Size will hurt returns. Look at Berkshire Hathaway - the last five things Warren has done have generated returns that are splendid by historical standards, but now give him $100 billion in assets and measure outcomes across all of it, it doesn't look so good. We can only buy big positions, and the only time we can get big positions is during a horrible period of decline or stasis. That really doesn't happen very often.

There's a lot wrong [with American universities]. I'd remove 3/4 of the faculty - everything but the hard sciences. But nobody's going to do that, so we'll have to live with the defects. It's amazing how wrongheaded [the teaching is]. There is fatal disconnectedness. You have these squirrelly people in each department who don't see the big picture.
