It was 40 years ago this month that two of President Gerald Ford’s top White House advisers, Dick Cheney and Don Rumsfeld, gathered for a steak dinner at the Two Continents restaurant in Washington with Wall Street Journal editorial writer Jude Wanniski and Arthur Laffer, former chief economist at the Office of Management and Budget. The United States was in the grip of a gut-wrenching recession, and Laffer lectured to his dinner companions that the federal government’s 70 percent marginal tax rates were an economic toll booth slowing growth to a crawl.
To punctuate his point, he grabbed a pen and a cloth cocktail napkin and drew a chart showing that when tax rates get too high, they penalize work and investment and can actually lead to revenue losses for the government. Four years later, that napkin became immortalized as “the Laffer Curve” in an article Wanniski wrote for the Public Interest magazine. (Wanniski would later grouse only half-jokingly that he should have called it the Wanniski Curve.)
This was the first real post-World War II intellectual challenge to the reigning orthodoxy of Keynesian economics, which preached that when the economy is growing too slowly, the government should stimulate demand for products with surges in spending. The Laffer model countered that the primary problem is rarely demand — after all, poor nations have plenty of demand — but rather the impediments, in the form of heavy taxes and regulatory burdens, to producing goods and services.
In the four decades since, the Laffer Curve and its supply-side message have taken something of a beating. They’ve been ridiculed as “trickle down” and “voodoo economics” (a phrase coined in 1980 by George H.W. Bush), and disparaged in mainstream economics texts as theories of “charlatans and cranks.” Last year, even Pope Francis criticized supply-side theories, writing that they have “never been confirmed by the facts” and rely on “a crude and naive trust in the goodness of those wielding economic power and in the sacralized workings of the prevailing economic system.” And this year, French economist Thomas Piketty penned a best-selling back-to-the-future book arguing for a return to the good old days of 70 percent tax rates on the rich.
But I’d argue — and not just because Laffer has been a longtime friend and mentor — that his theory has actually held up pretty well these past 40 years. Perhaps its critics should be called Laffer Curve deniers.
Solid supporting evidence came during the Reagan years. President Ronald Reagan adopted the Laffer Curve message, telling Americans that when 70 to 80 cents of an extra dollar earned goes to the government, it’s understandable that people wonder: Why keep working? He recalled that as an actor in Hollywood, he would stop making movies in a given year once he hit Uncle Sam’s confiscatory tax rates.
When Reagan left the White House in 1989, the highest tax rate had been slashed from 70 percent in 1981 to 28 percent. (Even liberal senators such as Ted Kennedy and Howard Metzenbaum voted for those low rates.) And contrary to the claims of voodoo, the government’s budget numbers show that tax receipts expanded from $517 billion in 1980 to $909 billion in 1988 — close to a 75 percent change (25 percent after inflation). Economist Larry Lindsey has documented from IRS data that tax collections from the rich surged much faster than that.
Reagan’s tax policy, and the slaying of double-digit inflation rates, helped launch one of the longest and strongest periods of prosperity in American history. Between 1982 and 2000, the Dow Jones industrial average would surge to 11,000 from less than 800; the nation’s net worth would quadruple, to $44 trillion from $11 trillion; and the United States would produce nearly 40 million new jobs.
Critics such as economist Paul Krugman object that rapid growth during the Reagan years was driven more by conventional Keynesian deficit spending than by reductions in tax rates. Except that 30 years later, President Obama would run deficits as a share of GDP twice as large as Reagan’s through traditional Keynesian spending programs, and the economy grew under Obama’s recovery only half as fast.
Supply-side economics was never just about slashing tax rates. As Laffer told me in a recent interview: “We also emphasized sound money, free trade and deregulation. It was a package of reforms to clear away the obstacles to increased economic output.”
