A Question about American Economy?

well it might have seem like they had it good during those times but you probably know that in 1929 the stock market collapsed, this crash was caused by the “poor aspects”, of the previous years which included a misdistribution of income and purchasing power (the rich were very rich and the poor were really poor and a huge gap in between), over expansion of credit (which seemed good just before the crash), over production of Industries (which inflated prices to historic levels), and an American tariff policy (interests rates of over 60% on imported product, this caused a decrease in product competition which then increased prices for the citizens of the US). So yeah the twenties are known as a time of prosperity but they are better known for having been a major contributor and catalyst to the Great Depression.
