In a primitive political system, power is transmitted through violence, or the threat of violence: military coups, private militias, and so on. In a less primitive system more typical of emerging markets, power is transmitted via money: bribes, kickbacks, and offshore bank accounts. Although lobbying and campaign contributions certainly play major roles in the American political system, old-fashioned corruption—envelopes stuffed with $100 bills—is probably a sideshow today, Jack Abramoff notwithstanding. Instead, the American financial industry gained political power by amassing a kind of cultural capital—a belief system. Once, perhaps, what was good for General Motors was good for the country. Over the past decade, the attitude took hold that what was good for Wall Street was good for the country. The banking-and-securities industry has become one of the top contributors to political campaigns, but at the peak of its influence, it did not have to buy favors the way, for example, the tobacco companies or military contractors might have to. Instead, it benefited from the fact that Washington insiders already believed that large financial institutions and free-flowing capital markets were crucial to America’s position in the world.

These personal connections were multiplied many times over at the lower levels of the past three presidential administrations, strengthening the ties between Washington and Wall Street. It has become something of a tradition for Goldman Sachs employees to go into public service after they leave the firm. The flow of Goldman alumni—including Jon Corzine, now the governor of New Jersey, along with Rubin and Paulson—not only placed people with Wall Street’s worldview in the halls of power; it also helped create an image of Goldman (inside the Beltway, at least) as an institution that was itself almost a form of public service.

As more and more of the rich made their money in finance, the cult of finance seeped into the culture at large. Works like Barbarians at the Gate, Wall Street, and Bonfire of the Vanities—all intended as cautionary tales—served only to increase Wall Street’s mystique. Michael Lewis noted in Portfolio last year that when he wrote Liar’s Poker, an insider’s account of the financial industry, in 1989, he had hoped the book might provoke outrage at Wall Street’s hubris and excess. Instead, he found himself “knee-deep in letters from students at Ohio State who wanted to know if I had any other secrets to share. … They’d read my book as a how-to manual.” Even Wall Street’s criminals, like Michael Milken and Ivan Boesky, became larger than life. In a society that celebrates the idea of making money, it was easy to infer that the interests of the financial sector were the same as the interests of the country—and that the winners in the financial sector knew better what was good for America than did the career civil servants in Washington. Faith in free financial markets grew into conventional wisdom—trumpeted on the editorial pages of The Wall Street Journal and on the floor of Congress. From this confluence of campaign finance, personal connections, and ideology there flowed, in just the past decade, a river of deregulatory policies that is, in hindsight, astonishing: • insistence on free movement of capital across borders; • the repeal of Depression-era regulations separating commercial and investment banking; • a congressional ban on the regulation of credit-default swaps; • major increases in the amount of leverage allowed to investment banks; • a light (dare I say invisible?) hand at the Securities and Exchange Commission in its regulatory enforcement; • an international agreement to allow banks to measure their own riskiness; • and an intentional failure to update regulations so as to keep up with the tremendous pace of financial innovation. The mood that accompanied these measures in Washington seemed to swing between nonchalance and outright celebration: finance unleashed, it was thought, would continue to propel the economy to greater heights.
