Greece seems to be in a serious mess financially, although the EC seems desperate for the Euro to survive the current crisis. It would appear Greece became a member of the Euro club based on rather dubious figures. Tax avoidance and early retirement ages appear to be a way of life in Greece and this is anathema to countries like Germany. If Greece doesn't get kicked out of the Euro, they certainly need to change. We will see what happens. I expect we'll see yet another fudge and somehow Greece will survive, although it is not clear for how long. I'm very glad not to be Greek right now. Life there must be very hard, especially if you have no work.
UPDATE 1726z: It sounds like Greece may be on the brink of a financial rescue. Time will tell.
