Lesson 4: Even from a conservative point of view, the welfare state is not all bad. G. K. Chesterton observed that you should never take a fence down until you understand why it had been put up. We should remember why the immediate post-Depression generations created so many social-welfare programs. They were not motivated only — or even primarily — by “compassion.” They were motivated as well by the desire for stability.

Social Security, unemployment insurance and other benefits were designed as anti-Depression defenses, “automatic stabilizers” as economists called them. When people lost their jobs, their incomes did not drop by 100 percent, but by 30 percent or 40 percent: they could continue to pay rent, buy food and sustain society’s overall level of demand for goods and services. State pensions created a segment of society whose primary incomes remained stable regardless of economic conditions. The growth of the higher-education sector and of health care had a similar effect…

Those who denounce unemployment insurance as an invitation to idleness in an economy where there are at least five job seekers for every available job are not just hardening their hearts against distress. They are rejecting the teachings of Milton Friedman, who emphasized the value of automatic stabilizers fully as much as John Maynard Keynes ever did. Conservatives should want a smaller welfare state than liberals in order to uphold maximum feasible individual liberty and responsibility. But the conservative ideal is not the abolition of the modern welfare state, and we should be careful of speaking in ways that communicate a more radical social ideal than that which we actually uphold and intend.
