Egypt under Hosni Mubarak near the end was notably different. There'd be heavily armed soldiers everywhere in all black. Unexplainable trucks of soldiers going everywhere. Locals wouldn't talk about certain places. I haven't been to China myself but my parents have and we've all been to Egypt and their impression was that the big cities were pretty much like a big European city or something like New York.
If it gives you any faith that my opinion isn't some Chinabot, I still remember The Economist's Red Moon Rising issue as frightening. I just think they're probably very good at keeping the authoritarianism inconspicuous and therefore more terrifying.
I don't deny your experience but this could be one of those Rashomon like situations where we all look at the same thing and come away with a different picture. And if it wasn't actually in your face then it'll discredit any argument about China's authoritarianism when people go there and see a prosperous happy people instead.
Is that because the West is acutely self-critical? Or is there something else going on here?
