The People’s Republic of China has been rolling out its system for spying on surveilling its citizens for a while now.  This is the system that develops social scores for every PRC citizen, and the system has bennies for achieving high scores:

…waived deposits on hotels and rental cars, VIP treatment at airports, discounted loans, priority job applications, and fast-tracking to the most prestigious universities.

Things that can detract from those high scores include

[j]aywalking, late payments on bills or taxes, buying too much alcohol, or speaking out against the government….
Other mooted punishable offences include spending too long playing video games, wasting money on frivolous purchases, and posting on social media….

Get too low a score, and citizens will be punished:

…los[e] the right to travel by plane or train, social media account suspensions, and being barred from government jobs.

The system isn’t all bad, though, assuming private citizens can learn their scores.  Those with low scores are showing themselves to be trustworthy—at least by their fellow citizens—and high scorers expose themselves as puppets of the government.
