Back to the discussion at hand, Euro break up. Maybe I am a fool, but I can't see that every happening completely. Each country could revert back to their own currency "easily" by busting out the presses, but Europe is pretty tightly stitched together. There would be a frightening period of financial woes as everyone struggles to adapt to the new situation.
How would that effect daily life for Phillipe and Emma Average?
Here is another foolish question. If the EU does start to fall apart, are any countries willing to stick with it and continue on? That is a very interesting question in my mind. There are 27 countries to start with, what if any 6, 9 or 12* decided to keep going? What would their role be in the situation?
