The 1950s era in the united states is described as “the affluent society.” what change does this term describe?

The 1950's era in the US being referred to as the "affluent society" represents a change in the American economy. After World War II, the American economy was booming thanks to the increased spending in developing military technology and creating the resources needed to help a post World War II Europe.

The result of this economic boom included lower unemployment rates and increased spending on material goods. A lot of this disposable income can be contributed in part to the GI Bill, which helped veterans of World War II pay for job training or pursuing a college degree. This then resulted in the development of the new middle class, which enjoyed modern luxuries like TV's and houses in the suburbs.
