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.
