Can too much optimism destroy an economy? This installment of the "American Experience" series suggests it was exactly that kind of unbounded thinking that lulled an entire country into a false sense of security before the stock market crash of 1929 hurled America into the Depression. This program revisits that transformative event and explores how both economic and political authorities made some very upbeat─and wrong─predictions about the future. 60 min. Standard; Soundtrack: English Dolby Digital stereo.
