M: The nineteen twenties were a time of economic progress for most Americans. During that time, many companies grew larger, creating new jobs. Wages for most Americans increased. Many people began to have enough money to buy new kinds of products. The strong economy also created the right environment for many important changes in the day-to-day social life of Americans. The nineteen twenties are remembered now as an exciting time that historians call the "Roaring Twenties." And today, we invited Professor Smith to talk about the nineteen twenties in the United States. Hello, Professor Smith.
W: Hello.
M: What’s the most important thing that the nineteen twenties brought to Americans?
W: The nineteen twenties brought a feeling of freedom and independence to millions of Americans, especially young Americans. Young soldiers returned from the world war with new ideas. They had seen a different world in Europe. They had faced death and learned to enjoy the pleasures that each day offered Many of these young soldiers were not willing to quietly accept the old traditions of their families and villages when they returned home. Instead, they wanted to try new ways of living.
M: New ways of living?
W: Yes, new ways of living. Many young Americans, both men and women, began to challenge some of the traditions of their parents and grandparents. For example, some young women began to experiment with new kinds of clothes. They no longer wore dresses that hid the shape of their bodies. Instead, they wore thinner dresses that uncovered part of their legs. Many young women began to smoke cigarettes, too. Many women also began to drink alcohol with men in public for the first time. And they listened together to a popular new kind of music: jazz. Young people danced the Fox Trot and other new dances.
M: Were there huge changes of people’s social values at that time?
W: Yes, at least among some Americans. People openly discussed subjects that their parents and grandparents had kept private. An important force behind these changes was the growing independence of American women. In nineteen twenty, the nation passed the Nineteenth Amendment to the constitution, which gave women the right to vote. Of equal importance, many women took jobs during the war and continued working after the troops returned home. Also, new machines freed many of them from spending long hours of work in the home washing clothes, preparing food, and doing other jobs.
