IF proof were needed of the maxim that the road to hell is paved with good intentions, the economic crisis in Europe provides it. The worthy but narrow intentions of the European Union’s policy makers have been inadequate for a sound European economy and have produced instead a world of misery, chaos and confusion.

There are two reasons for this.

First, intentions can be respectable without being clearheaded, and the foundations of the current austerity policy, combined with the rigidities of Europe’s monetary union (in the absence of fiscal union), have hardly been a model of cogency and sagacity. Second, an intention that is fine on its own can conflict with a more urgent priority — in this case, the preservation of a democratic Europe that is concerned about societal well-being. These are values for which Europe has fought, over many decades.

Certainly, some European countries have long needed better economic accountability and more responsible economic management. However, timing is crucial; reform on a well-thought-out timetable must be distinguished from reform done in extreme haste. Greece, for all of its accountability problems, was not in an economic crisis before the global recession in 2008. (In fact, its economy grew by 4.6 percent in 2006 and 3 percent in 2007 before beginning its continuing shrinkage.)

The cause of reform, no matter how urgent, is not well served by the unilateral imposition of sudden and savage cuts in public services. Such indiscriminate cutting slashes demand — a counterproductive strategy, given huge unemployment and idle productive enterprises that have been decimated by the lack of market demand. In Greece, one of the countries left behind by productivity increases elsewhere, economic stimulation through monetary policy (currency devaluation) has been precluded by the existence of the European monetary union, while the fiscal package demanded by the Continent’s leaders is severely anti-growth. Economic output in the euro zone continued to decline in the fourth quarter of last year, and the outlook has been so grim that a recent report finding zero growth in the first quarter of this year was widely greeted as good news.
