Even a crappy government, which is widely known to be one of the least efficient ways to manage anything.

What's the percentage of multi millionaires or billionaires that are involved in effective, life changing philanthropy for large swaths of people?

a lot of people would disagree here, see the (correct, based) coup of the aus govt over the judiciary allowing them to at will deport migrants, or the controls on going outside in australia

I chalk up China's governmental competence to the number of scientists and engineers involved in their government. It may be authoritarian and a bit of a nightmare, but unlike the majority of other governments in the world you have a few decision makers in there who have some clue how the world actually works. Most other government are run by lawyers, career bureaucrats, delusional ideologues, or leaders who inherited their position either officially via some line of succession or de-facto via institutional nepotism.

There are some of all those categories in China's government, but there are also apparently enough people who actually know how to do things in the real world.

This might be a relevant story I read today on China.

Only a small percentage of billionaires do incredibly valuable things, but those who do are doing things that I can't imagine the US government of today ever doing. The US government would be having meetings to schedule the meeting to discuss the meeting schedule, or fighting over culture war issues.

I think that the government has been sabotaged. Intentionally impairing it's functions to justify the critiques of functionally.

"I want to make the government small enough to drown in a tub"

"Government doesn't work, elect me and I'll prove it"(that one's a joke but conveys the point)
