BERKELEY – If you asked a modern economic historian like me why the world is currently in the grips of a financial crisis and a deep economic downturn, I would tell you that this is the latest episode in a long history of similar bubbles, crashes, crises, and recessions that date back at least to the canal-building bubble of the early 1820’s, the 1825-1826 failure of Pole, Thornton ampamp; Co, and the subsequent first industrial recession in Britain.
