Moral responsibility / culpability for present and historical injustices, necessarily has to have reasonable limits in order to be applied in any useful way.
One could say, for example, “I am complicit in the deaths of three dozen workers who died in a factory in Bangladesh which collapsed while they were making fake branded shirts because I own an original branded shirt, and if people like me didn’t elevate the importance of these brands, there would be no drive to duplicate them in substandard garment factories in the developing world which were not built under any safety standards. Those workers died because of me”, but this is an unreasonably abstract and indirect level of culpability. It borders on narcissism. This ‘Butterfly Effect” style of imposing / accepting moral responsibility can only paralyze you, or else drive you mad.
