The major advanced economies should not just be worried about Greece, it said, they should be worried about themselves. If the huge debt levels of the major economies prompt the world financial markets to wonder if those debts will be honoured, so that the markets take a set against sovereign debt in general, the majors, too, will be in big trouble.

They are committed to generous pension payments and healthcare spending for their retiring baby boomers at a time when, for many countries, their populations will be falling.
