From Groucho Marx on the Crash of '29 : "Everything I bought increased in value. [...] You could close your eyes, rest your finger anywhere on the huge wall board, and the stock you had just bought would immediately start going up. I never made a profit. It seemed absurd to sell a share at thirty when you knew that within a year it would double or triple in value.[...] Every now and then some financial prophet would publish a gloomy article warning the public that prices were out of proportion to true values and reminding them that what goes up must come down. But hardly anyone paid attention to these foolish conservatives and their idiotic words of caution. [...] I think the only reason I kept living was the comforting conviction that all my friends were in the same situation. Even financial misery, like that of any other species, prefers company." Some resemblance to later events and to the euphoria of the moment when the stock market dances its own music and the orchestra of the world economy takes another rhythm, is pure coincidence.
