Bet, it's just been like a hundred comments of the same three talking points from liberals in .world. The reason it's not just bad because it's a "bigger authority" is because of the class character of the state, as well as the subject of the oppression. Lenin dedicated an entire book to the subject, State and Revolution. As to how it applies to China and why popular support among a revolutionary government despite capital and billionaires being allowed to exist, one of the best pieces I've ever read on the subject is this https://redsails.org/china-has-billionaires/

It's good that there's a bigger authority than capital, the party rules through popular consent, and they chose Xi Jinping as well as the people that do the actual legwork of the anti corruption drive to be the executors of that will. If the US had a popular mandate that prevented corporate abuses, Luigi Mangione wouldn't have needed to be incarcerated, he would have already gotten his surgery.
