This is just silliness. Rich people got rich under capitalism by providing things people want for the best price. They're rich because they owns shares in valuable businesses that people want to buy the products of.
Some people get rich, on average by merit. And everyone gets the products they want at a low price. Can you imagine if the only cars available were made in the USSR, like Ladas? They were terrible because there was no capitalism, and so no competition. But if you'd rather have abysmal cars but know that no one got rich making them, I guess that's...a choice?
Sure!
Like the Sacklers who got rich by... providing the best opiates. Or Zuck, who got rich by... destroying the fabric of our society. Or Big Oil, which got rich by... destroying ecosystems and dooming us all. Or United Fruit Company which got rich by... brutally colonizing Latin America.
It's almost as if the profit motive optimized for profit, not any other outcome that was in any way beneficial to anyone but the ones... profiting.
