It reminds me of how Sam Altman recently said: "I'd rather hear from candidates about how they are going to make everyone have the stuff billionaires have instead of how they are going to eliminate billionaires." But the hyper-wealthy don't just have _stuff_, they also have power to make decisions affecting society -- to buy elections, to buy social networks, to influence which countries we do AI chip deals with, to start new cities, and so forth. A world in which everyone has the same amount of this decision-making power is probably not a world in which billionaires exist.
