Can you talk about the specific performance of the "noisy era" in America?

The 1920s was a short and special period in American history, which was called "turbulent years", referring to 19 19 years after the end of World War I and 1929 years before the American economic collapse.

Several factors constitute the particularity of this era. First of all, the United States is at the intersection of old and new history, and the vigorous development of capitalism has enabled the United States to quickly enter the industrialized modern society from agricultural civilization. At the same time, the United States, which entered the war in the late World War I, made a fortune in the war because it was not hit hard by the war, and changed from a pre-war debtor country to a creditor country. At that time, the main government implemented a "laissez-faire" economic policy, that is, it advocated letting the free market run by itself. The less government intervention in economic activities, the higher the efficiency of economic operation. This created a miraculous "Coolidge Prosperity Era". So at that time, the domestic economic situation in the United States was excellent, the transportation, minerals and construction industries expanded rapidly, and the electrical appliance and automobile manufacturing industries suddenly became stubborn. Cars, electrical equipment, household machinery, processed food and clothing began to enter people's homes, bringing unprecedented comfort to the lives of many Americans. Real estate trading and stock market are particularly active, and some speculators get rich overnight in this kind of gambling industry. The amount of wealth has become the standard to judge a person's success, and people begin to make money blindly, make "fast" money and earn more money; At the same time, American hedonism, Spencer's theory of evolution and James's pragmatic philosophy prevailed in the United States, and traditional puritan moral concepts and religious beliefs such as "thrift" were gradually replaced by consumer hedonism such as pursuing personal wealth and enjoying material life.
