Have you been there? Have you ever done business with them? Have you looked at the development China has been able to achieve in the past 20 years instead of squandering it on BS like the US does with all it's money?
Literally half the people in the 23 million public jobs in the US have worthless jobs that do nothing but suck up tax money. Everyone in those jobs participates in pension scams to the tune of hundreds of billions every year. How much money we funnel over to places like Ukraine for scams amounts to more than the entire defense budget of China.
Pretty much the entirety of our government and public apparatus is rotten to the core at this point. Not saying China doesn't have corruption, but they have a much stronger sense of Nationalism that facilitates at least some functions of their policy and government to develop the nation for the good of China. We don't have that in the US anymore. We have people all out for themselves with no real rules or sense of national identity to contain those actions so those actions just go where ever, they aren't retained within the country so the plebs get to feed at the trough or get to eat the scraps. There is no impetus in the US anymore for the political system to move in a way that benefits it's citizens at least in some form. China does have that impetus in their political system.
