The correct answer to this open question is the following.
The era of the 1920s had another name, which related to money; the name was "the Roaring 1920s."
This was a period of economic prosperity in the United States. Citizens had money and they spend it on necessary and unnecessary things such as cars, furniture or homes. Most people used credit, generating high debts. The problem was that after the United States stock market crashed on October 29, 1929, millions of Americans lost their jobs, companies had to close, and banks went into bankruptcy. It was the beginning of the Great Depression.
