In 1929, a crisis among speculating capitalists prompted poorly conceived and excessive reactions, leading to a deep and prolonged depression. Less than four years later, US President Franklin D. Roosevelt’s newly elected government passed the Glass-Steagall Act, which prohibited commercial banks from trading securities with clients’ deposits.
1929年，一场投机资本家之间的危机让人们产生了误判和过度反应，导致了一场深刻的长期危机。不出四年，美国总统富兰克林·罗斯福的新当选政府通过了格拉斯-斯蒂格尔法案（Glass-Steagall Act），禁止商业银行用客户的存款交易证券。
