A certain amount of wealth concentration is necessary to organize the production and distribution of goods efficiently and invest in research and development, but it’s the competition that drives people to strive for efficiency. Too much wealth concentration produces the opposite result where one person is able to make irrational and inefficient decisions, which negatively impacts everyone below them. See: Elon Musk. If was less wealthy, to the point where he couldn’t afford to fuck up, then he wouldn’t be able to screw over the people beneath him.
