What were some ways consumerism and race relations changed in the 1920's and 1950's respectively?

In both the 1920s and 1950s, we had a real, sizable middle
class, with money to spend and some time on their hands, so the decades share a
materialist feeling in society and the money with which to buy new consumer
goods.

Race relations aren't quite as similar between those
two time periods, in that during the 1920s, Jim Crow segregation laws were still typical
in many states, and while the Harlem Renaissance advanced black culture, very few whites
in the country recognized it as a social achievement.  If anything, the 1920s were more
racist than decades past, but more about immigrants than about only
African-Americans.

The 1950s represented a decade of racial
struggle for civil rights, with support from the Supreme Court in 1954's Brown
vs. Board of Education and for the first time, support from a significant
number of whites.
