Here are a few examples of positive social credit:
Do you serve your nation in the military?
Do you bear and raise children? Are you a caregiver for other types of dependents (parents, disabled)?
Are you able-bodied and employed or at least employable? How stable is your job?
Are you currently enrolled as a student, seeking a degree or graduation?
Are you in stable housing; can you meet your personal needs daily without difficulty?
Are you free of mental illness, and medications thereof?
Have you got a criminal record, imprisonment or legal troubles in your past?
So you can see that autistic people will typically start with poor social credit, and it will not be possible for them to get on top of that.
Now a wealthy nation in peacetime can afford to do the "Welfare State" thing and support people with negative social credit, due to pro-life values and the fact that you can indeed exploit the poor and infirm for Medicaid and SNAP bucks, no matter what (RFK's claim that "they don't pay taxes" is specious if they're consumers).
But I think the USA can no longer claim to be "wealthy" and our claim on peace is tenuous at best. When those two run out then what is left? Nothing but a little Aktion T4. Difficult decisions will need to be made and this is why people with "poor social credit" are going to be under the microscope.
