Nothing succeeds like failure, as the saying goes. And nowhere is this dismal truth more evident than in our financial regulatory system, one year after the bankruptcy filing of Lehman Brothers. Even though calamitous lending practices laid waste to the nation's economy, surprisingly little has changed about how the financial arena operates and is supervised. Sure, a couple of venerable brokerage firms have vanished, but many of the same players remain on the scene, in the same positions of power. Senior regulators who stood idly by for years as financial firms built their houses of cards have been rewarded with even bigger jobs or are jockeying for increased responsibilities. The Federal Reserve Board, for example, wants to become the financial system's uber-regulator, even though its officials did nothing as banks made deadly decisions to lend recklessly and leverage themselves to the max. Awarding increased power to those who failed in their oversight duties flies in the face of all notions of accountability. Yet those in the public sector ask us to believe that regulators who snoozed during the credit bubble will be alert to emerging problems on their beats when the next mania begins. That's asking a lot, isn't it? Here's a novel thought. Instead of creating more regulations to try to prevent this kind of mess from recurring, why not figure out how to hold regulators accountable when they perform as poorly as they did in recent years? Taxpayers must protect themselves against two things: the corrupting influence of bureaucratic self-interest among regulators and the political clout wielded by the large institutions they are supposed to police. [And] taxpayers must demand that the government publicize the costs of efforts taken to save the financial system from itself.
