In 1981, traditional Republicans supported tax cuts, matched by spending cuts, to offset the way inflation was pushing many taxpayers into higher brackets and to spur investment. The Reagan administration’s hastily prepared fiscal blueprint, however, was no match for the primordial forces — the welfare state and the warfare state — that drive the federal spending machine.

Soon, the neocons were pushing the military budget skyward. And the Republicans on Capitol Hill who were supposed to cut spending exempted from the knife most of the domestic budget — entitlements, farm subsidies, education, water projects. But in the end it was a new cadre of ideological tax-cutters who killed the Republicans’ fiscal religion.

Through the 1984 election, the old guard earnestly tried to control the deficit, rolling back about 40 percent of the original Reagan tax cuts. But when, in the following years, the Federal Reserve chairman, Paul Volcker, finally crushed inflation, enabling a solid economic rebound, the new tax-cutters not only claimed victory for their supply-side strategy but hooked Republicans for good on the delusion that the economy will outgrow the deficit if plied with enough tax cuts.
