MAN: Education was another important force behind the social changes of the
1920s. More and more Americans were getting a good education. The number of students attending high school doubled between 1920 and 1930. Many of the schools now offered new kinds of classes to prepare students for useful jobs.
Attendance at colleges and universities also increased greatly. And colleges offered more classes in such useful subjects as teacher training, engineering, and business administration.
Two inventions also helped cause the social changes. They were the automobile and the radio. The automobile gave millions of Americans the freedom to travel easily to new places. And the radio brought new ideas and experiences into their own homes.
Probably the most important force behind social change was the continuing economic growth of the 1920s. Many people had extra money to spend on things other than food, housing, and other basic needs. They could experiment with new products and different ways of living.
