How did many Americans in the 1920s afford exclusive luxury items?

In the 1920s, many Americans were able to afford exclusive luxury items due to a combination of rising incomes, easy credit, and the proliferation of consumer goods. The post-World War I economic boom led to increased wages, which allowed more individuals to participate in consumer culture. Additionally, the advent of installment buying enabled people to purchase expensive items by making small down payments and paying off the balance over time. This era of consumerism was further fueled by advertising and the desire for status, making luxury items more accessible to a broader segment of the population.
