Not OP, but you can easily find statistics on public transportation, wages, healthcare/life expectancy, government approval, ecological policies, technological development, energy use and so on.
Collecting these statistics takes too much time for a single comment, but you can find statistics from a wide variety of sources such as the world bank, imf, rand (western sources), or Chinese sources like Chinese government data (like from the national burea of statistics).
Either way, the data is quite favorable for China and Chinese citizen’s quality of life. They have a higher life expectancy than Americans, world class public transport, the world’s best green energy industrial complex (by such a huge margin that in comparison, the rest of the world might as well not try). It is quite a decent place to live in, baring the issues with low wages, youth unemployment and high working hours (compared to western nations, as least until the fascists de-develop the west enough).
No it boils down to “we kicked the Japanese fascists out and have a pretty decent standard of living now compared to the rest of the world”
