In my opinion one of the main causes for the stock market crash was do to the agricultural recession and buying on the margin which lead to the banks also going broke. And without support from the banks, the economy wasn't able to bound back from the recession. It felt really good when you were doing well in the stocks. It encouraged you to continue to invest more and keep earning money. However, when the stocks crashed, it left you feeling hopeless and kinda lost. In most cases the owners of the stock lost everything and were so greatly in debt to the bank that there was no chance they could repay it. This caused the banks to go bankrupt which lead into the Great Depression. One of the first signs that the stocks were going to crash was the start of the agricultural recession. The price of bread was so low that farmers were considerably poorer. However, most people didn't know the signs or at least didn't see the signs.
