One of the pillars of capitalism is that the entire economy is more efficient when decision making power is dispersed as close as possible to the people making economic decisions aka what they buy.

When we have ended up in a situation where a handful of people are making all the economic decisions because they have all the money, there is no functional difference between that situation and a command economy.

If you’re a believer in capitalism as a tool to eliminate scarcity you should view the existence of billionaires(adjust for inflation) over the longer term as policy failures that are eroding capitalisms ability to create more and more.
