CONFUSING CAUSE AND EFFECT:

[T]he biggest economic threat, by far, comes from continental Europe.

Now that German growth has stumbled, the euro area is on the verge of tipping into its third recession in six years. Its leaders have squandered two years of respite, granted by the pledge of Mario Draghi, the European Central Bank's president, to do "whatever it takes" to save the single currency. The French and the Italians have dodged structural reforms, while the Germans have insisted on too much austerity. Prices are falling in eight European countries. The zone's overall inflation rate has slipped to 0.3% and may well go into outright decline next year. A region that makes up almost a fifth of world output is marching towards stagnation and deflation.

Optimists, both inside and outside Europe, often cite the example of Japan. It fell into deflation in the late-1990s, with unpleasant but not apocalyptic consequences for both itself and the world economy. But the euro zone poses far greater risks. Unlike Japan, the euro zone is not an isolated case: from China to America inflation is worryingly low, and slipping. And, unlike Japan, which has a homogenous, stoic society, the euro area cannot hang together through years of economic sclerosis and falling prices. As debt burdens soar from Italy to Greece, investors will take fright, populist politicians will gain ground, and--sooner rather than later--the euro will collapse.
