Answer:
During the 1920s, economic growth in the United States occurred rapidly and then slowed down.
Step-by-step explanation:
The 1920s have been called the Roaring 20s because America's economy grew 42 percent. U.S. victory in World War I gave the country a global power, and, in a very short time, many industries were born and mass production spread new good into every household. This was a decade of tremendous prosperity. However, the following decade, the 1930s, represented the most severe depression in US history.
