In this entire debate, you haven't made any logical arguments. You have only started and ended with a single assumption, that being in possession of great wealth inherently makes you a bad person.
I'm currently reading the Ender's Game series, and just finished the 2nd book, Speaker for the Dead. Mild spoilers follow.
Ender has been doing a lot of near-lightspeed travel, so due to time dilation, he is now about 3000 years old. He has a sentient AI friend who has been making investments in his name during his travels, so he has inadvertently become possibly the wealthiest human in existence. However, he never asked his friend to make those investments, and he only found out when he asked for her help with a problem one day. His wealth is rarely mentioned for the rest of the book.
He wasn't living a life of luxury before he found out about his wealth, and still doesn't, and he's too busy with protagonist stuff to devote any time to philanthropy; money just isn't part of his identity or decision making. He helps lots of people in his adventures, but not using his money, and most things he or they need can't be bought anyway. His wealth is just another tool to be used as needed, but it's far from his most useful or important one.
