Final answer:
In the 1920s, the United States witnessed a substantial rise in consumerism, with notable increases in the use and production of automobiles, electric home appliances, and entertainment options like cinema and radio. The mass production of these consumer goods made them accessible to the average American and changed leisure and consumption patterns, contributing to the rise of a modern urban culture.
Step-by-step explanation:
During the 1920s, the United States experienced a significant boom in consumerism, with a marked increase in the production and use of various products. As factories switched from war-time production to consumer goods, Americans, with saved capital from the lean war years, were eager to spend on new conveniences and luxuries. The proliferation of automobiles, particularly due to Henry Ford's Model T, transformed mobility and spurred related industries. The era's prosperity also fueled growth in electrification and the purchase of electric home appliances such as refrigerators, washing machines, and vacuum cleaners, whose sales skyrocketed from only a few thousand to over a million by the decade's end. Furthermore, entertainment mediums like cinema and radio became increasingly popular, changing patterns of leisure and consumption.
With more disposable income, Americans spent less on staples and more on non-essentials and leisure, contributing to a burgeoning consumer culture punctuated by advertising and credit sales. Mass production made previously luxury goods accessible, transforming societal values and boosting industries across the board, from steel to rubber to furniture and home decorations. The significant changes also reflected in urban population growth, supporting a shift away from rural, small-town values toward a more modernist, urban culture.
