They seem to be missing a critical piece - for the horrors that China inflicted on its own population, it also become a preeminent world power and pulled millions out of poverty.
What seems to be happening elsewhere is an organized robbery of state institutions by politicians and oligarchs, with oppression and censorship used to keep people from pointing out the obvious.
Maybe they're not paying attention to the part of that cycle where they start falling out of windows.
> pulled millions out of poverty
but firstly the policies of the very same party put millions into poverty and famine
Becoming a preeminent world power was orthogonal to them instituting mass domestic surveillance, public humiliation, and selective ethnic cleansing.
