In my opinion, FDIC had the most impact during the Great Depression in America. It insured peoples money, so if anything were to happen to their money or savings accounts at the bank, they were guaranteed to get their money back. Back then it only insured up to $5,000 but it was better than them not getting anything back at all. So if anything were to happen, they would have some money to support their families. They didn't have to worry so much anymore and had more trust in banks.
