Mises on interventionism

Authors of economics books, essays, articles, and political platforms demand interventionist measures before they are taken, but once they have been imposed no one likes them. Then everyone-usually even the authorities responsible for them-call them insufficient and unsatisfactory. Generally the demand then arises for the replacement of unsatisfactory interventions by other, more suitable measures. And once the new demands have been met, the same scenario begins all over again.
