My eyes were opened to this when I was able to have an honest and open conversation with an African-American friend (I'm not American and never understood the history), and he described the level of victimisation that is passed on from generation to generation after traumatic events that span multiple generations. There is a deep wound in American history that is unique to the African-American experience.
Museums like this try to capture some of it. But really, America should be looking to Truth and Reconciliation commission type of platforms that has worked in other places. Finish what was started in the Reconstruction-era, or continue to suffer from this wound.
Well, you don't get to define what's "worse-off" for another culture. And should that give us pause about current policies that may cause the same behaviour later on?
