But we’re comparing whites and blacks in America, so the old “but people are starving in Africa” doesn’t apply here.
So why is there a disparity of family wealth between whites and blacks in America? Any alternative theories? Because “but the bombing of Dresden…!!!” does not explain it.
As for your question, I do not have any theory. A viable theory would have to explain the variation of the black-white gap across the US.
Looking for data, I found a graph mapping the differences of average black and white income (not wealth) across U.S. states:

If racism was the only root explanation, Pennsylvania would be more racist than Georgia and Wisconsin more racist than South Carolina. That does not seem plausible to me.
