The Fall of America, Inc.

Reaganism (or, in its British form, Thatcherism) was right for its time. Since Franklin Roosevelt's New Deal in the 1930s, governments all over the world had only grown bigger and bigger. By the 1970s large welfare states and economies choked by red tape were proving highly dysfunctional. Back then, telephones were expensive and hard to get, air travel was a luxury of the rich, and most people put their savings in bank accounts paying low, regulated rates of interest. Programs like Aid to Families With Dependent Children created disincentives for poor families to work and stay married, and families broke down. The Reagan-Thatcher revolution made it easier to hire and fire workers, causing a huge amount of pain as traditional industries shrank or shut down. But it also laid the groundwork for nearly three decades of growth and the emergence of new sectors like information technology and biotech.

Internationally, the Reagan revolution translated into the "Washington Consensus," under which Washington—and institutions under its influence, like the International Monetary Fund and the World Bank—pushed developing countries to open up their economies. While the Washington Consensus is routinely trashed by populists like Venezuela's Hugo Chávez, it successfully eased the pain of the Latin American debt crisis of the early 1980s, when hyperinflation plagued countries such as Argentina and Brazil. Similar market-friendly policies are what turned China and India into the economic powerhouses they are today.

And if anyone needed more proof, they could look at the world's most extreme examples of big government—the centrally planned economies of the former Soviet Union and other communist states. By the 1970s they were falling behind their capitalist rivals in virtually all respects. Their implosion after the fall of the Berlin Wall confirmed that such welfare states on steroids were an historical dead end.

Like all transformative movements, the Reagan revolution lost its way because for many followers it became an unimpeachable ideology, not a pragmatic response to the excesses of the welfare state. Two concepts were sacrosanct: first, that tax cuts would be self-financing, and second, that financial markets could be self-regulating.

Prior to the 1980s, conservatives were fiscally conservative— that is, they were unwilling to spend more than they took in in taxes. But Reaganomics introduced the idea that virtually any tax cut would so stimulate growth that the government would end up taking in more revenue in the end (the so-called Laffer curve). In fact, the traditional view was correct: if you cut taxes without cutting spending, you end up with a damaging deficit. Thus the Reagan tax cuts of the 1980s produced a big deficit; the Clinton tax increases of the 1990s produced a surplus; and the Bush tax cuts of the early 21st century produced an even larger deficit. The fact that the American economy grew just as fast in the Clinton years as in the Reagan ones somehow didn't shake the conservative faith in tax cuts as the surefire key to growth.

More important, globalization masked the flaws in this reasoning for several decades. Foreigners seemed endlessly willing to hold American dollars, which allowed the U.S. government to run deficits while still enjoying high growth, something that no developing country could get away with. That's why Vice President Dick Cheney reportedly told President Bush early on that the lesson of the 1980s was that "deficits don't matter."

The second Reagan-era article of faith—financial deregulation—was pushed by an unholy alliance of true believers and Wall Street firms, and by the 1990s had been accepted as gospel by the Democrats as well. They argued that long-standing regulations like the Depression-era Glass-Steagall Act (which split up commercial and investment banking) were stifling innovation and undermining the competitiveness of U.S. financial institutions. They were right—only, deregulation produced a flood of innovative new products like collateralized debt obligations, which are at the core of the current crisis. Some Republicans still haven't come to grips with this, as evidenced by their proposed alternative to the bailout bill, which involved yet bigger tax cuts for hedge funds.
