Another lesson is how much libertarianism managed to disguise itself as conservatism. A smaller state and lower taxes are always desirable, but the claim that government cannot be used to advance substantive moral goods is a long-peddled libertarian fiction. If public policy can incentivize single parenthood and lifelong government dependency, as much of the current system does, then there is no principled reason existing funds cannot be reallocated to strengthen marriage, encourage family formation, and promote healthier social arrangements.
But hey, maybe we should just listen to the libertarians and encourage more gambling and porn use instead. Because muh freedum matters most!
If I understand the establishment conservatives correctly, we should not reform a 30-year-old entitlement program to stop incentivizing single parenthood because it would be better abolish the entire 91-year-old welfare state, which no one even pretends to think is possible.
