I don't have the slightest clue what she does with her money. Supposing she were to give lots of money to charity, for example...is it still bad that she has that money, if she does good things with some of it?
@AlexanderKingsbury @peterbutler hanging onto that much money fundamentally means you are not doing enough good things with it to offset the harm you are doing.
