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.
One of the main goals of socialism is increase in general well-being and ensuring comprehensive development for ALL members of society. Not sure if i formulated this correctly in english but you get the the idea. Social credit system is a tool, it can be used for good or bad, but it should not be the goal.
