That's not a problem with the arguments, it's a problem with your worldview. If everything that happened that you directly benefit from 'wasn't you' and you therefore refuse to redress the wrongs done and on top of that refuse those same benefits to others that doesn't - in my opinion - make you a nice or reasonable person. Similar arguments have been put forth by the beneficiaries of crimes in the past and failed. You're obviously entirely welcome to your worldview and your feeling that if it wasn't you that did it that you can ignore the source of your wealth but such individual selfishness can add up to collective selfishness and that's the sort of thing that will sooner or later garner a collective response. And by then no amount of 'it wasn't me' will be of help because it was you, all along. By helping to correct these wrong and by being open to others being helped you serve yourself because you keep the social pressures at a manageable level. Ignoring them for too long leads to them spilling over.
