As far as I can tell, the people burning everything down aren't even particularly likely to be black, efforts to spin this as some kind of necessary fight back against racism by people who've been suffering not withstanding. The folks cheering it on and advocating for this to their audiences definitely aren't - they're largely white, middle-class techies and journos and other well-off educated folks who aren't worried about their own communities burning.
The real pain - at least on the inter-generational poverty and deprivation side - is that in six months, the average American small business isn't going to exist in heavily-black neighbourhoods, and that probably won't change much in six years, and other businesses are probably going to be pretty thin on the ground there too. Apparently some places never recovered what they lost in the sixties race riots.
Though I expect that the consequences of the police actions to stop this will also be anything but temporary. It seems to take years of careful work to rebuild trust between police and the community they serve, and to restructure policing to be less hostile and dangerous.
