I think this was a good read, but as a US citizen with no connection to China, it's hard to say. I imagine what this kind of post would sound like but in the reverse, someone in China commenting on these kinds of social dynamics for US citizens, and I can't help but think it'd be a pretty crude characterization of our reality.
I would have really liked it if the author offered their perspective of the US version of these dynamics in a more one-to-one way. It'd let me "calibrate" their characterizations based on how accurate their version of the US side of this is based on my experience.
Regardless, I do think this attempts to at least apply nuance to this kind of discussion, and, of course, the author made it clear that they're aware of the kinds of faults I'm describing, so at least there's that.
