What Buffett Believes But Cannot Prove

"Most people think Buffett is a perpetual bull on the stock market. This is not true. There have been many occasions when he has been cautious about the stock market and even times when he has forewarned of impending doom — 1969 and 1999. However, Buffett is unabashedly bullish on the United States. He has never been shy to express his belief that the United States offers tremendous opportunities to anyone who is willing to work hard. He is upbeat, cheerful, and optimistic about life in general.

Conventional wisdom holds that it is the young who are the eternal optimists and that as you get older, pessimism tilts the scale. But Buffett appears to be the exception to this maxim."
