Answer:
Mass consumption played a major role in the Great Depression.
The economic downturn of the late 1920s was caused by a number of factors, and mass consumption was one of the most prominent.
As consumer spending declined, businesses had to reduce their production levels and lay off workers.
This further exacerbated the economic downturn, as fewer people had money to spend on goods and services.
This led to further declines in production, leading to even more layoffs.
The cycle of reduced consumer spending and production eventually resulted in the Great Depression.
