"[Lawyers who file class-action securities suits] is not a group you would want to marry into your family. "That said, more than half the time the people being sued by the Lerach firm are guilty of outrageous conduct. The problem is, they don't mind (suing) the other half. They are an equal opportunity litigator."

The beauty of a financial institution is that there are a lot of ways to go to hell in a bucket. You can push credit too far, do a dumb acquisition, leverage yourself excessively - it's not just derivatives [that can bring about your downfall].

I find it quite useful to think of a free-market economy - or partly free market economy - as sort of the equivalent of an ecosystem. Just as animals flourish in niches, people who specialize in some narrow niche can do very well.

We regard using [a stock's] volatility as a measure of risk is nuts. Risk to us is 1) the risk of permanent loss of capital, or 2) the risk of inadequate return. Some great businesses have very volatile returns - for example, See's [a candy company owned by Berkshire] usually loses money in two quarters of each year - and some terrible businesses can have steady results.

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 democracies are prone to inflation because politicians will naturally spend [excessively] - they have the power to print money and will use money to get votes. If you look at inflation under the Roman Empire, with absolute rulers, they had much greater inflation, so we don't set the record. It happens over the long-term under any form of government.

If it happens every year like clockwork, what's so extraordinary about it?
