I have to admit I have trouble parsing what is being said.
But I don't think the author realizes how recent the nuclear family is as a concept. The pain of a woman living alone in an empty signle-family home caring for her infirm husband with nobody else to talk to is not some god-given truth that liberalism pretends is not your due, it is a direct result of liberal/calvinist individualism where that couple can't depend on the village or on younger generations of the family for support in kind because anyone who does help in kind is taxed twice.
Society was broken for profit (and more importantly to prevent civil uprisings) before the range of OOP's historical awareness. Even the Christian embrace of suffering is a tool of submission.
Spontaneously caring for other people is joyous. The fact that capitalism has warped it into a miserable transactive hell is by design.
