You asked, more or less, 'what's the question'? To which i would respond, is there a EU-wide taxation framework, and how much cohesive force does it provide the EU?

Geography (Pireaeus + Thessaloniki) + Probable Divided Political Coalition (PSAOK+New Democracy+Syriza) + Odious Debt (Escrow Account + Bailout # 3) = Muddle Through?

'Smart money' is also considering two additional scenario's just in case however, Grexit and GIIPS exit.
