Final answer:
In the 1920s, American consumers embraced a consumer culture, indulged in the use of credit, and were heavily influenced by mass marketing to purchase material goods, reflecting the era's economic productivity.
Step-by-step explanation:
During the 1920s, American consumers reacted to the heightened economic productivity by embracing the values of a consumer culture. This decade was marked by a significant shift in consumer behavior as people began to buy on credit and as mass production made goods more accessible at lower prices. The introduction of new technologies in entertainment and transportation also facilitated this change. Americans did not prioritize saving money in banks; rather they seized the opportunity to enjoy the newfound prosperity by purchasing material goods. Mass marketing and advertising played a crucial role, persuading consumers that owning more goods equated to a good life.
