I might get flame for this but. Social credit system might be a way for us to get rid of money and achieve a classless, money less society. People can work hard and get a good social credit score. With a good social credit score, the benefit will be free housing, free healthcare and free food, water and electricity… etc. If you have a low social credit score, you can always improve by being a better person and contribute.
I will say that basic necessities should be provided for in an ideal society (keyword ideal) for even the worst people imaginable. I would imagine social credit better being used to warrant things like luxuries, things that use up greater amounts of resources, the ability of the individual to wield power over society such as positions which demand a high level of trust and responsibility, etc.
I will also say that to me at face value this sounds a lot like money as it already exists, albeit perhaps non-accumulable to the degree we see capitalists hoarding wealth (which is important) and non-transactable (ditto, except perhaps in a soft way such as a person with high credit endorsing someone or something).
Definitely not a money expert though.
