Shouldn't be unbelievable. It is all relative for him. He wants money so he has "more" than others. Doesn't do him any good if people he hate get money as well.
Like that joke about the divorced guy who finds the lamp with the genie in it on the beach.
He is walkin' along, and bumps his toe on a magic lamp. Genie comes out and says "You have freed me from my prison, so I shall grant you 3 wishes. Just know that whatever I grant you I shall give twice as much to the person you hate most...Your wife's divorce attorney."
Guy says "Well, I am tapped out from the divorce and had to go into debt to buy my children's Christmas presents. I would like to be rich enough that I never have to worry about money again."
Genie says "Granted, and the lawyer's new wealth is twice your own."
The man says, "I would like the family heirlooms that were lost in a fire years ago back"
"Granted again, and know that the lawyer possesses all of his lost treasures as well. What is your final wish?"
The man says "I would like you to take out one of my kidneys and half my liver and give them to kids who really needs them..."
