During the 1920s, the booming stock market roped in millions of new investors, many of whom bought stock on margin. The 1920s also witnessed a larger bubble in all kinds of credit - on cars, homes, and new appliances like refrigerators. In the years after the 1929 crash, the credit-based economy fell apart. By 1933, Wall Street and the nation's banking and mortgage industries were left for dead. The searing experience helped plunge the economy into a deep depression and spooked an entire generation of investors.
