I don't buy this in the slightest. One person's fun cannot be at another person's expense, even if "they don't mind." Yeah, how hilarious, one character is getting 3 times the loot anyone else is getting - that's not fun, that's just irritating. And the game quickly devolving into character vs character revenges, nah, not for me. The DM spent time writing a world and a story, and I want to experience it.
