Another way to put it—and here lies the legacy of Keynes—is that a free society is an interplay between a more-or-less permanent framework of social commitments, and the oasis of economic liberty that lies within it. The nontrivial question is: What risks (to health, loss of employment, etc.) must be removed from the oasis and placed in the framework (in the form of universal health care, employment insurance, etc.) in order to keep liberty a substantive reality, and not a vacuous formality? When Hayek insists welfare is the road is to serfdom, when Nozick insists that progressive taxation is coercion, they take liberty hostage in order to prevent a reasoned discussion about public goods from ever taking place. "According to them, any intervention of the state in economic life," a prominent conservative economist once observed of the early neoliberals, "would be likely to lead, and even lead inevitably to a completely collectivist Society, Gestapo and gas chamber included." Thus we are hectored into silence, and by the very people who purport to leave us most alone.
Thanks in no small part to that silence, we have passed through the looking glass. Large-scale, speculative risk, undertaken by already grossly overcompensated bankers, is now officially part of the framework, in the form of too-big-to-fail guarantees made, implicitly and explicitly, by the Federal Reserve. Meanwhile, the "libertarian" right moves to take the risks of unemployment, disease, and, yes, accidents of birth, and devolve them entirely onto the responsibility of the individual. It is not just sad; it is repugnant.
