A spectre is haunting Europe – the spectre of sovereign default. All the powers of old Europe have entered into a holy alliance to exorcise this spectre: Brussels and Frankfurt, Angela Merkel and Nicolas Sarkozy, French socialists and German Christian Democrats. Churchillian doctors, they prescribe blood, sweat and tears – fiscal consolidation, tax increases and spending cuts. They swear, for the umpteenth time, that they will never surrender: Greece will be saved, Italy and Spain will not be abandoned and the rating of France will not be downgraded. In the face of adversity, they assure us that what cannot be achieved by austerity can be achieved by more austerity. An epidemic of holier-than-thou fiscal virtue is spreading throughout Europe and is fast transforming a series of uncoordinated fiscal retrenchments into a euro-wide contraction with dire implications for growth and employment.

To be sure, eurozone policymakers are in a maddening situation. The threat to monetise public debt, which in the old days could be waved by each country to remind investors it need not ever default outright, has been removed from national arsenals. No one knows for sure whether it will ever be brandished from Frankfurt or if European treaties even allow it. Eurobonds would have every economic merit but they hurt Germany which, having been left on its own to finance reunification, is understandably cold towards die Transfer-Union. Creating separate northern and southern euro areas would probably precipitate the end of the single market – and where would France fit? Wide-ranging fiscal reform designed to increase tax revenue equitably, while sorely needed, is a pipe dream: it requires elusive European co-ordination in an area in which the temptation to compete is strong and it is best done at its own pace – not under the pressure of fickle market sentiment or rising sovereign spreads.

Add to this powerlessness the terrifying failure of the old engine of European policymaking (putting the cart before the horse in the hope that the cart will conjure up the horse) and you will understand the ghoulish visions gripping our leaders. Monetary union has not begotten the expected fiscal union. Imposing, as a substitute, austerity plans from Brussels or Frankfurt, or racing to be first to impose “golden rule” constitutional strictures on parliaments that should remain sovereign in fiscal matters is stoking the fire of civil unrest. The English Civil War and American Revolution were ignited by much less. It would be wise to recall, as John Hampden did in contesting the Ship Money tax levied by Charles I, that what leaders have no right to demand, a citizen has a right to refuse.
