"There's nothing unique about this; it is something which happens every twenty or thirty years, because that is about the length of the financial memory. It's about the length of time that it requires for a new set of suckers, if you will, a new set of people capable of wonderful self-delusion, to come in and imagine that they have a new and wonderful fix on the future." -- John Kenneth Galbraith, discussing the Wall Street crash of 1929, on the PBS television program, American Experience, episode "The Crash os 1929" (aired November 2008 -- in my area, on 2008-11-10)
