The marekt thought that debt was held in common and bond yields were the same for everybody, now they have to make it clear to markets that this is not the case. Because if it was the case, then ALL the debt is held by everybody.

It does not need a PhD in Game Theory to see what the likly outcome of such a system is.
Greece is in the unfortinate situation of beeing the case were this choice has to be made. Its not all their fault, but its also not their fault.
This is just on of the problems of the EU and the Eurozone.
Its my beliefe that if debt should be assumed commonly, it will break up the EU because no voters in any country would agree to this.
It is really sad, and if you want to blame somebody, its the eurocrats who have steamrolled over many economists and many others who have point out the idiocy of their plans.
