"The scale of economic misery caused by the European Monetary Union in Southern Europe has been accentuated by the deteriorating condition of European banks. Healthy banking systems are essential for economic growth, but well-performing banks also depend on functioning economies. The euro has choked off the engine of the European economy. The lessons emerging from the eurozone crisis are clear: there is no economic justification for a federal Europe or a single currency."
