Lets take Germany like example
Bundesbank president were warning Merkel and EBC,that what thayaredoing is driving Europe,including Germany to catastrophe,all thatausterity,raising debts EBC QE,all that can create huge problems
And what nothing,Bundesbank ,germany central ban voice is nothing,nobodycare,In Eurozone national central banks importance is limited to almost zero.EBC is only onecentral bank for all Eurozone countries
That is even hard to believe ,becouse eurozone countries are independent countries
Euro has been created like a political project,practically money are in Germany hands
I guess this EMU thing is a large plan by central banks, and since long ago those banks are already merged. Maybe the ECB owner is the same as GCB owner, so they treat all countries in Euro zone the same, don't want to spoil Greece government. However, just like each child have different personality, each country have its own spending habit
It seems their merger did not reach Nordic countries therefore Denmark Sweden Norway did not join EMU, still printing their own money, but get larger volatility on foreign currency market as their currency scale is too small (Swedish currency had been attacked by Soros during 90s and followed by long recession, but they still prefer their own currency) Maybe the nordic country are facing the same problem as Greece, but as long as they can print their own money (Swedish central bank has dropped to negative interest long ago), they still can hang on
Finland is with Euro,nordic country,thay are now facing very deep crisis
Much better for any country is to manage his own monetary policy
