General consensus in Europe is it's hard to see Greece staying in the Euro zone - there is a limit to how much bail out money they can expect and they themselves will not want to bear more austerity.

(Of course them they will be back to drachma, massive devaluation and debts still in Euros)

My biggest concern with the global economy (as with climate change and a few other big issues) is the divergence of opinions as to how to deal with the problem, and the various political axes that get ground while supposedly finding a solution.

Watching the US from overseas there seem to be a lot of half truths, lies and poor analogies coming from all quarters and so the chance of finding a solution and implementing it seems low.
