Just as many Chinese citizens are proud of their country and culture, there are lots of people in the US who are proud of their country and culture. Are there lots of hypocrites in the United States? Yes. Are there lots of naive people? I mean people still love Trump now while the rest of the world laughs at us. The people in both societies are flawed so let's put that aside.
If we look at both systems (and not as individuals), the US as a whole makes an attempt to do what's right and the system attempts to correct bad behavior. The original founders tried to prevent any one person from usurping power through checks and balances. As Trump tries to upend the country, the Supreme Court restricts what he can do but also tries to ensure the presidency retains power against the legislative branch. Trump has very little power against the Supreme Court and his Supreme Court appointees have voted against him several times already.
Citizens in United States can take to the street to protest against change. Does it always work? Most of the time no. But occasionally, with George Floyd's case, some changes are happening. When individual citizens has their rights taken away, it is possible to sue the government. When this is taken to the Supreme Court and the citizen wins, change happens.
These things will not necessarily get us to a better place but the mechanism for the people to make the change is enshrined in the constitution. Fortunately, this mechanism does eventually guide us to the right place. So far.
As far as I can tell, this kind of corrective behavior does not work in countries like Russia, China and North Korea. It's citizens cannot demand change. What these countries do have is a level of efficiency that democracies will never match. I am envious of this. I am jealous of China's high speed rails and it's ability to erect large cities and hospitals in a matter of months and days.
No doubt United States is in a bad place right now. It has lost its leadership status in the world, it's citizens are sick and dying with a virus that the rest of the world has controlled, and citizens are demanding to not be murdered by their police. However, Trump will most likely be voted out in the fall. Congress is slowly passing laws for better police reform. Counties and states who do not agree with the President covid policies can work against the President's demands to better protect their citizens. Yes there will be problems. Some bad actors will get away with unethical and immoral behaviors. However, the system will attempt to correct the problem. This is why Western democracy is regarded higher than dictatorships in countries like Russia, China and North Korea. The system in United States will give its citizens a better chance to weather the storm than a country with dictatorship.
