@CalamityJane,
Merkel (and the Germans) may have a point in that the limitations in central government, inherent in the EU, don't allow sufficient supra national budgetary discipline to sustain the foundations of an ECB heavily involved in autonomously extending credit in the name of all the member countries. That indeed was the factor that led them all to abandon the stability pact that accompanied the creation of the Euro and the factor that enabled Greece (and other Eurozone countries) to run up such dangerous levels of debt.
I also think that the accelerating European demographic collapse - of all but the UK, France and the Scandanavian countries - is likely a core factor here in both creating the problem and fostering different perspectives on what must be done about it.
It's conundrum. The EU has made great strides over the past three decades chiefly by bypassing issues pertaining to EU-wide real governance, substituting for it various bureaucratic controls. They may have gone as far with that as is possible, and now find themselves in a head-on confrontation with competing national interests and priorities.
