As I look at what passes for responsible economic policy these days, there’s an analogy that keeps passing through my mind. I know it’s over the top, but here it is anyway: the policy elite  central bankers, finance ministers, politicians who pose as defenders of fiscal virtue  are acting like the priests of some ancient cult, demanding that we engage in human sacrifices to appease the anger of invisible gods.

Hey, I told you it was over the top. But bear with me for a minute.

Late last year the conventional wisdom on economic policy took a hard right turn. Even though the world’s major economies had barely begun to recover, even though unemployment remained disastrously high across much of America and Europe, creating jobs was no longer on the agenda. Instead, we were told, governments had to turn all their attention to reducing budget deficits.

Skeptics pointed out that slashing spending in a depressed economy does little to improve long-run budget prospects, and may actually make them worse by depressing economic growth. But the apostles of austerity  sometimes referred to as “austerians”  brushed aside all attempts to do the math. Never mind the numbers, they declared: immediate spending cuts were needed to ward off the “bond vigilantes,” investors who would pull the plug on spendthrift governments, driving up their borrowing costs and precipitating a crisis. Look at Greece, they said.

The skeptics countered that Greece is a special case, trapped by its use of the euro, which condemns it to years of deflation and stagnation whatever it does. The interest rates paid by major nations with their own currencies  not just the United States, but also Britain and Japan  showed no sign that the bond vigilantes were about to attack, or even that they existed.
