I think you can it's just shifted by several decades because China took a long dark detour through the Cultural Revolution. QoL exploded in the US in the Post War period, partially imo because we were the only industrialized economy that didn't have significant homeland attacks during WW2 so the US got a straight shot to the top of the heap. China got a similar QoL lift through a similar path, mass manufacturing (this time business taken from the US by being far cheaper) and growth of in country expertise. Now even China is feeling a similar cost squeeze drawing some business to smaller neighbors. They're also just so much larger they can sustain a larger gradient between coasts that look closer to '1st' world costs and poorer interiors where cheaper manufacturing can be done.
Sure, but what's relevant is what sort of political and cultural pressures we're all experiencing now. Maybe China is just a few years behind on the same crunch trajectory we're on, maybe not, but that doesn't matter much to what's going on today.
Well if the complaint is China is experiencing/experienced much more recently a big uplift in QoL vs the US it's because China was behind the US in it's economic development so it had easier gains to make.
We're no where near experiencing the same political and cultural forces because the US and China are vastly different on many axes both in their structure and culture and importantly we're very very different economically.
