Peter Boettke's call for charitable readings before damnations is reasonable and simpatico. I do object, though, to his use of "interventionism" in the Hayek sense, and even more in the vulgar sense. It has become a codeword and shibboleth for a particular world-view that developed when labor and landless proletarians generally began to have some influence, however meager, on the state. Before the Wagner Act, for example, most of the power of the state was marshaled against labor, while corporations ran wild. Before the Emancipation Proclamation the state enforced slavery. Adam Smith noted that the state was mainly involved in protecting property. That was not intervention? A similar phrase is "social engineering", usually said with a sneer. Our former city utilities Director, for example, called it social engineering to provide lifeline power and water rates for customers with low incomes; but not to use declining block rates to help the biggest customers, that's different! Chicago Schoolers call it intervention to impose a minimum wage law, but are silent on the greater intervention of the payroll tax and withholding (Milton Friedman's baby) and retail sales taxes. Unearned increments to land values are given preferential low tax rates, or virtual exemption often, while nurses and industrial toilers and brain surgeons are subject to the full fury of tax rates on "ordinary" income. Did Hayek ever call that "intervention"? "Intervention" and "social engineering" are used when the customary domination of public policy by the rich, huge, and powerful is modified, however slightly. Did Hayek use them more objectively? His popularity on the chicken-a-la-king circuit leads one to doubt it. I am open to conviction, and hope I am wrong, but as Harry Truman said, "Show-me".
