The 1920s saw social and economic changes in the United States. The period after WWI was characterized by isolationism, as seen in laws restricting immigration and the Red Scare targeting radicals. Culturally, the decade witnessed the rise of new technologies like automobiles, radio, and movies. The stock market boom led many to speculate, but the economy was unstable and ultimately collapsed with the 1929 crash. Overall, the Roaring Twenties represented a time of social liberalism, economic growth, and increasing consumerism in America.
