“We shall again take for granted the availability of a system of public relief which provides a uniform minimum for all instances of proved need, so that no member of the community need be in want of food or shelter.”

That’s from The Constitution of Liberty, “definitive edition,” p. 424. Yes, it comes as part of Hayek’s argument against mandatory state unemployment insurance. But it reflects a fundamental understanding that no one should go without food or shelter, and that it is the duty of the government to ensure this minimum level of existence. “The necessity of some such arrangement in an industrial society is unquestioned,” he wrote (p. 405).

The standard that Hayek simply assumed would exist goes beyond merely keeping poor people alive. In a wealthy society, he thought it inevitable that it would become “the recognized duty of the public to provide for the extreme needs of old age, unemployment, sickness, etc.” (p. 406). On this basis, he even endorsed the idea of compulsory insurance, such as the individual mandate of the Affordable Care Act.

I’m not claiming that Hayek would have supported Obamacare — he almost certainly would have favored less government involvement than the system of state-level exchanges. But on the questions of welfare and government intervention in insurance markets, he was to the left of the entire Republican Party today.
