The point here was that credit scores do not only rate your own behavior, but also those of people around you. If your neighborhood is bad, your credit score might reflect that instead of your own performance as a debtor. And if your neighborhood becomes hip and gains a better reputation, your credit score might improve even though you're still the same person.
Capitalism sometimes rewards those who provide value, but more often than not has no problem rewarding people for spouting self-righteousness.

Define righteous? Define immoral?
Capitalism rewards providing actual value to people. It doesn't reward shallow niceties and self-righteousness, those are common.
