Greece is in finiancial trouble again and are looking to borrow even more money to pay their debts. Hardly a sustainable system. It is a beautiful country, good people, and they basically make more than they spend but they are crippled by debt and a widespread belief that the state owes them a living. No-one is talking about Grexit at the moment but that will no doubt come.
On the other side of Europe, the UK is threatening a Brexit, with a referendum later this month. Personally I hope they will leave, they have always been in only to create trouble for the rest of Europe and to stir up dissent and create conflict. The EU would be better off without them. Good riddance !
