If you can do that cross checking why can’t the Chinese government ?
Discussion
They do. That's why they regularly have anti-corruption purges and etc., but that is not effective. You can't cure a centralized system's corruption with random controls. Controls are only to identify problems, not to fix them. That is a core rule of Quality Assurance (which we learned from the Japanese).
Also, you don't know if the people in the control functions are not also corrupt. This is a deep, cultural problem inherent to centralized systems, that any problem becomes endemic, so that even the auditors end up in one the game.
Decentralized systems are messier and more chaotic, and harder to steer, but problems from one section tend to not spread as quickly to the others.
Side question: have you been to China?
Nope.
I think it's an irrelevant question, tho. There is no evidence that a random Chinese resident would know any more about Chinese corruption than someone with decades of industrial experience interacting with Chinese suppliers, competitors, and coworkers, as both an internal auditor and tester.
I have a question for you:
Do you have any evidence to the contrary? Do you have proof that Chinese national statistics are reliable, and that the supply-chains and all levels of government are generally honest, efficient, and free of corruption?
I believe two things: Chinese government is probably full of shit, to what extent relative to Europe or Canada or the usa? (I’m unsure)
Also You’re full of shit claiming to know the extent of the fullness of shit of Chinese government
Okay, so you're just a troll.
No, I’ve actually been to China though
Having been to China (rural China) about 10 years ago and having family there
They’re doing better and things are improving there.
