The Causes of The Great Depression / FDR Memorial Site
According to respected economist John Kenneth Galbraith the causes of the Great depression were unhealthy corporate and banking structures, an unsound foreign trade, much economic misinformation and the "bad distribution of income".
Consider those economic conditions to today's economic conditions. I hope you are thinking about it on a day the stock market fell 500+ points.
