What was a contributing factor to the growth of middle-class consumerism after world war 2?

A key factor contributing to the growth of middle-class consumerism after World War II was the economic prosperity experienced in many Western countries, particularly in the United States. The post-war boom led to increased disposable income, enabling families to spend more on goods and services. Additionally, the rise of mass production and advertising, coupled with the expansion of credit options, made consumer products more accessible to a broader audience, further fueling the desire for ownership and consumption.
