Most people do create wealth. That is exactly how those wealthy people become wealthy - by having someone create wealth for them, and then appropriating most of it.
Leveraging ownership of capital, more specifically.
But lest we forget, all this wealth is still protected by people with guns. These days, those people normally work for the state rather than directly for the wealthy, but the latter can also leverage their wealth to steer politics such that the state does violence on their behalf to protect their property as needed.
What fraction of that time goes to subsidizing the exponentially wealthier? We could just tax the hell out of the rich and and make better lives for the vast majority of us, while wealth hoarders still get to “win” at the game of life.
