Wrong. Try speaking out against the US government in any meaningful way and you'll be murdered by it. Dissent is not welcome here and you will be punished for it.

How is this different than our credit score system and 80% of people living paycheck to paycheck? Employers check it, housing checks it, travel is about to implement face scanning. Not seeing a huge difference here. There aren't even many good jobs (https://amp.usatoday.com/amp/1809629002If). If we don't fully have it yet, we sure as shit will soon.
Everything we do is tracked, watched, listened to, recorded. Look up and view all of the easily hackable cameras loaded with back doors literally everywhere. It's really not much different than what we're told about China. Talking in work Slack I often get "move to Signal" because our workplaces are authoritatian and strip you of your rights when you walk in the door.
Are there even any examples so far of China's social credit having any effect on anyone?
It's hilarious that the evidence you give to back up your position is a wikipedia article about a well-known stain on American history from forty years ago.
