Physical public goods, like public transport or public restrooms or sidewalks, are left filthy and full of hobos because enforcing basic laws is racist (in the critical race theory sense of disparate impact).

Social public goods, like norms related to civility and manners and integrity and competence, are actively attacked because one or the other of them impinges on someone's conception of freedom or justice.

It's not surprising that people don't want to expand the scope of public goods when we can't be trusted with the ones we've already inherited.
