European federalists know that the single currency zone will need at least a ten-fold increase in direct EU taxes (currently 1.28% of GDP) for there to be any prospect of European social stability.
At the time of writing, all the major Euro countries are in crisis, with Germany close to joining the fold, with growth set to halve next year (assuming Euro-zone problems get no worse).
But on that fateful Friday, when the North American plate slid over the Pacific plate along a subduction zone running 130km (80 miles) off the Pacific coast of northern Japan, the shock leapt from the first segment to a second and on to a third, extending the fault zone some 400km and increasing its intensity more than 30-fold.
