Explanation:
The post-World War II United States went through a period of unprecedented economic prosperity for many white Americans that coincided with black Americans' intensifying the struggle for civil rights and economic justice. Racial and ethnic minorities were left out of the postwar boom because racism still allowed them to be excluded from employment opportunities, which fueled the postwar boom. Since they were making less they were largely excluded from the ability to live in the suburbs and remained in cities themselves.
