Not a new idea by any means, but one that I've always found interesting and thought-provoking. I've always liked Noam Chomsky's succinct rejoinder along these lines:
Q: [H]ow can you justify living a bourgeois life and driving a nice car?Just so. It's an obvious point, but so easy to lose track of in our culture, even once you're aware of the dynamic at work.
A: ... When I go to visit peasants in southern Colombia, they don't want me to give up my car. They want me to help them.
And it really is a distraction, as teeth-gnashing over one's contribution to gentrification, for example, ends up being "white guilt" of the most pointless sort: you either waste your time twisting yourself into knots, trying to explain how you're actually not part of the problem; or you shrug your shoulders and resign yourself to being an irredeemable oppressor, and thus liberated from any responsibility to change the system.
