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.

Wesco had a market capitalization of $40 million when we bought it [in the early 1970s]. It's $2 billion now. It's been a long slog to a perfectly respectable outcome - not as good as Berkshire Hathaway or Microsoft, but there's always someone in life who's done better.

To us, investing is the equivalent of going out and betting against the pari-mutuel system. We look for a horse with one chance in two of winning, and that pays three to one. In other words, we're looking for a mispriced gamble. That's what investing is, and you have to know enough to know whether the gamble is mispriced.

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

Common stock investors can make money by predicting the outcomes of practice evolution. You can't derive this by fundamental analysis - you must think biologically.

Wall Street has too much wealth and political power.

Berkshire's whole record has been achieved without paying one ounce of attention to the efficient market theory in its hard form. And not one ounce of attention to the descendants of that idea, which came out of academic economics and went into corporate finance and morphed into such obscenities as the capital asset pricing model, which we also paid no attention to. I think you'd have to believe in the tooth fairy to believe that you could easily outperform the market by seven-percentage points per annum just by investing in high volatility stocks.
