Question

many americans had more money and more leisure time.
many americans had less money and less leisure time.
many americans had electricity and fewer household chores.
many americans had cars that were affordable and popular.

Explanation:

In the 1920s, economic growth led to higher incomes for many Americans. With more disposable income and increased leisure time (due to factors like shorter work - weeks in some industries), people had the means and time to consume more goods and services. Having more money and leisure time is a fundamental cause of consumerism.
Electricity and fewer chores (while beneficial) are more about changes in household work rather than a broad - based cause of consumerism. Affordable cars were a result of consumerism (Henry Ford's mass - production techniques made cars more affordable, which was part of the consumer - driven economy but not the root cause). Having less money and leisure time would not promote consumerism.

Answer:

Many Americans had more money and more leisure time.
