For how "homogeneous" China is considered, regions often define people more than ethnicity or racial groups. A common greeting that most people ask is "Where are you from?" Both migrant workers and the growing middle class now have the ability to travel anywhere in the country to further their futures. Back in the 70s or even the 90s this mixing of people was pretty much unheard of. Shanghai culture was only in Shang…
The culture, custom and language difference is definitely more drastic than it is in the U.S. I was somewhat bullied as a young kid in Shanghai because I couldn't speak Shanghainese that well.
However value is mostly not as divisive as it is here. I'm talking about the same kind of success is valued and worshipped throughout the country, urban and countryside alike. People also largely share similar family value, similar world view, and even similar opinions of domestic and foreign politics. In the U.S. I get the impression that everyone wants the best for the country, but they just drastically disagree on what an "ideal America" should look like. It's looking more and more like one side's paradise is the other side's nightmare.
Personally I theorize a lot of that is due to decades of centralized media, propaganda and a top down, heavily scrutinized education system, but in this case one can't help but wonder if democracy is always better judging by the extreme polarization of media bubble and social value in American society. In fact, we reached the level that democracy is only tolerated in the U.S. but not liked by most people. If you give a theoretical ballot/proposition to Hilary voters that strip Trump voters of voting rights and vice versa, I have a feeling a significant amount of voters across both sides will vote YES, but not admit in doing so.
But that's discussion for a different day.
