In 1929, while the market was rising, seemingly without limits, there were few critics. Based on eight years of continued prosperity, presidents and economists alike confidently predicted that America would soon enter a time when there would be no more poverty, no more depressions - a "New Era" when everyone could be rich. The Great Crash is mostly associated with October 24, 1929, called Black Thursday, the day of the largest sell-off of shares in U.S. history, and October 29, 1929, called Black Tuesday, when investors traded some 16 million shares on the New York Stock Exchange in a single day.
