The EU's drive to expand the eurozone at all costs is stupid.
It was more idealistic than stupid.
The Euro was seen by political idealists as a tool to forge a stronger european union.
Since something like this was never tried before problems were bound to arise.
Surely one could put all the blame now at the US/UK credit crunch crisis but that would only be
halfway true as this only accelerated the inborn frailties of this current euro zone...
Two such diverging economies as for example a high tech tools manufacturing industry needs other rules than a mainly tourism industry economy...that's now a widely accepted fact.
That's why changes have to be made and will be made!
But I doubt that Greece (or Ireland for that matter) will be better off alone all by themselves.
If these countries default without any helping hand people will again resort to fleeing the country and selling their labor in the EU.
Their countries having no chance whatsoever to get back to their feet as nobody will help them monetary nor with investments as the EU will do.
Neither the EU nor the EURO are to blame for their problems but they are their best chance not to fall back into dark times.
