Businesses continued to go bankrupt, especially banks. From 1929 to 1932, 5,000 banks, which tended to be too small and unregulated, went out of business. In New York, 10,000 of the 29,000 manufacturing firms closed. However, not all businessmen lost out in the depression. Overall, the very rich remained prosperous. Multi-millionaires, such as J D Rockefeller, kept their wealth in items like gold and property so they did not suffer as much as small businesses, workers and farmers when the banks failed.
