Hate to break this to you, but billionaires are not a “class” in the same way merchants or workers are. The problem with being a billionaire is that by the mere fact of being one, you are already on the wrong side of history. If any of them had morals, they would immediately divest enough wealth to others to become not a billionaire. But they don’t. Because they are still billionaires. Including the one in your example.

As the person above said, there are no good billionaires, full stop.
