If he wanted to, he could do something about the way people think of the wealthy and the way they use their wealth. His influence is only sourced from wealth, I don't think he gets it. He might be smart, but he's not any smarter about people or the world, nor more energetic and motivated, than thousands of others who just haven't gotten where he is, and might be low-paid in non-profits, universities, and government.

Instead, he's not doing a thing to change anyone's mind that the rich are rather more spoiled and entitled-acting than everyone else.
