Which undemocratic feature of american society did progressives not take steps to correct

I go with that answer that person said its correct

There were many such things, for example, systematic racism. African-Americans were still living in poverty or didn't have civil rights and segregation was strong. They could only join white communities if they were musicians or things like that where they would have to play for white guests of parlors. It wasn't until the 60s that the African-American people were given their civil rights.
