It already exists through other means. Any arrest (!) or conviction is likely to show up in a background check, and most employers besides very small ones conduct background checks.
If you can't get a job because you can't pass a background check, then you have a pretty low chance of affording to live. I mean sure, you can still walk around in society and book plane tickets if you somehow get money (something you can't do in China with a bad score).... but you are already teetering on homelessness, bankruptcy and re-imprisonment under our current US system.
