Final answer:
The industry most closely associated with the rise of consumerism in 1920s America was the automobile industry, supported by advancements in the home appliance industry and innovations in the advertising industry.
Step-by-step explanation:
The industry most closely associated with the rise of consumerism in America during the 1920s is the automobile industry. The automobile revolutionized American society, changing the way individuals traveled and lived, and becoming a symbol of personal freedom and status.
Coupled with the mass production of cars, the introduction of credit purchases allowed more people to own a car, leading to increased consumer spending.
In addition to automobiles, the home appliance industry also saw rapid growth during this period. The widespread electrification of homes played a significant role in this expansion, as new products like refrigerators, washing machines, and radios became household necessities.
Advances such as planned obsolescence encouraged continual consumption, as items were designed to wear out or become outdated quickly, prompting further spending.
Major shifts in advertising strategies and the rise of national marketing campaigns also propelled consumerism. The advertising industry used new tactics to manipulate emotions and desires, convincing Americans that owning the latest products was a key aspect of achieving the 'good life.'
Department stores and chain stores further facilitated this culture shift by offering a wide assortment of goods and employing modern marketing techniques to attract a growing consumer base.
