Watch out for what you wish for
Surely a strong £ means weakened attractiveness for export? The very thing that our government is hanging its hat on for our 'continued' recovery.
As to whether or not Germany and France should or should not bail out Greece/Italy, it is the very presence of these economies in the EU over the last 10 years that has kept the currency exchange rates enjoyed by Germany and France to be relatively low valued in a world sense and therefore kept them exporting in a way that they could not out of the Euro (the Mark and Franc would have strengthened and exports reduced accordingly).
So Germany, and to a lesser extent France (the two major economies in the Eurozone) have benefitted from sucking in the minnows of southern europe and can count, in not a small way, their current strength as a direct result of the make up of the Eurozone.
Conversely of course, Greece, Ireland, Portugal, Spain have all been able to benefit from interest rates only previously available to Germany and France - this being the direct cause of the reckless borrowing that they were tempted into.
So should they share the pain? A bit, at least, I would say as the reality is that the only way that the Euro can really work is Federal control of borrowing and therefore collective responsibility for Eurozone debt (so they would have shared that pain anyway). They should have set up a central bank in the firts place, controlled their members more tightly and perhaps they wouldnt be in this mess.
I too am glad we never went into the Euro. I recall with some mirth a great deal of argument for it because it would be easier to go on holidays and not have to change our money up. Well its more expensive now for sure but at least we can sit outside the problem to a degree
But coming back to watching what you wish for - if they fail and their economies go under - then we are for it anyway, we'll all be back in a very severe recession that will threaten the world economy. Sounds like fun eh?
