This is absolutely true and needs to be discussed, as even within the context of the black community. The vast majority of the disparities we see today are entirely caused by post war era institutional racism and are near entirely removed from anything that happened during reconstruction or as a result of slavery.

Black people in major cities had equal levels of wealth when compared to the Catholic and Jewish immigrants before the great depression, but after the war and the new deal, blacks were left with nothing when these other white groups were totally folded into broader white society.
