From a historical point of view, the injustice against blacks was perpetrated mostly by governments. Private business does not go in for race-based policies, because it means excluding paying customers. And this is precisely why racialists, nationalists, and hard-core bigots have always opposed liberal capitalism: it includes and excludes based on the cash nexus and without regard to features that collectivists of all sorts regard as important. In the imagined utopias of the national socialists, the champions of commerce are hanged from lampposts as race traitors and enemies of the nation.
