None of this detracts from the fact that these laws are ultimately relatively clear in their restrictions, compared to China's social score.
Theft is theft. Drug possession is drug possession. Had these "unfairly" targeted individuals followed the law, they would not be subject to its penalties.
Sure, I recognize that very few of us are perfectly law abiding citizens. But I have trouble with the notion that heavier police presence, and heavier sentencing for repeat offenders, are somehow unfair phenomena, and these alleged transgressions far too often are lumped together with actual institutional inequity.
In other words, one must not conflate subjectivity in sentencing and policing with some kind of ingrained, institutional caste system, so long as laws are followed as written. If you wish to stay out of the felon caste, do not break obvious laws, like those regarding drug possession. If you do not agree with such laws, work to change them.
