Bezos as an example built a great service. An exchange of value between willing customers and what he created happens repeatedly. Therefore he earned the billions. Thats how it works. The more value you create for the most people makes you more money. And I cant think of a more fair system.
Those Amazon servers don't magically teleport the packages to the customers.
All because he's lobbied, and continues to lobby, to not pay enough taxes. The tax system is unbelievably unfair.
Those who "create value" often don't. The continuing enshittification of everything is removing value from customers, yet the CEOs who are forcing it on their customers are getting paid vast salaries. We all know that they're destroying value and that their organisations will eventually be replaced by ones that actually value customers, but they continue to be rewarded.
You have a very naive view of capitalism.
