ROBERT HIGGS: All Government Policies Succeed in the Long Run.

People label a policy as a failure because it does not bring about its declared objective. . . .

These objectives are not the policy-makers’ real objectives, but only the public rationales they use to disguise their true objective, which invariably is to bring about the enrichment, aggrandizement, and other benefit of the politically potent individuals and interest groups that pack the decisive punch in the policy-making process—for example, those who can most effectively threaten legislators with affirmative punishments or the withdrawal of financial support for the legislators’ reelection if the string pullers’ interests are not served.
