How are they going to pay for all this?
Oh...they are not.
If they default on their debts no-one will lend them any more money. They will have to leave the Euro and start from scratch, which is possibly what they want.
If any company ran its accounts the same way Greece did when it submitted its application to join the Euro the directors would be looking at some serious pokey.
But this is the problem - the EU has taken a group of countries who have little in common and decided to try and shoe-horn them all into a one size fits all economic policy.
Quite how anyone thought there could be a meeting of minds, culture and currency in countries that have absolutely nothing in common save as to approximate geographical location is beyond me.
