It would have been worth reminding readers that the debt crisis in Italy and other euro zone countries is first and foremost a political crisis. The European Central Bank (ECB) can just print euros which can be used to address any potential default risk among its member countries. There would be little obvious economic downside to this policy since most European counties have large amounts of unemployment and excess capacity due to inadequate demand.
If there is a risk of default it is because the ECB has decided to make an obsession out of its 2 percent inflation target. This shows that numerology can be a very dangerous religion when it is held by central bankers.
