Whoa whoa whoa, just because both systems have problems and have some similarities doesn't mean no one can complain. I'm not gonna defend the US's problems because it doesn't matter! It's easy to see the Chinese system as morally bad. Why? Because free speech and dissent are the mechanisms by which we improve our ideas and systems. This social credit system backed by the already authoritarian government will further cement the will of the party powers over the will of the people. And everyone should care about a billion people.
We're agreeing. My point is that we should care about a billion people in China and a billion people in the West and billions everywhere. You're right that free speech and dissent are how we make change. I'm questioning the Western perspective because it seems like free speech and dissent are reaching limits as well. Dissent as you like, it probably won't work, and you'll probably suffer consequences in the commercial sphere, albeit not formally in the political or national spheres. We should keep complaining until it gets better. I just wonder if the complaints ever get heard in good faith.
