> I wonder if Americans/Westerners are capable of acknowledging the things that their countries get wrong

I feel like this is practically a sport in America. We love to criticize the government and everything it does wrong. That's part of democracy: the fact that Trump was voted out was very much a collective "we fucked up/this is wrong" where we decided to go a different path. In China, on the other hand, that is not allowed. We certainly do have issues in the US, but a lack to self-criticism does not count among them
