Well I found that copy pasted bit of crap to be very blinkered in it's view, so the fact that some countries needed bailout is due to a single currency ? There were never any bailouts before the euro ? Of course there were but they were funded by the banks at a relatively crippling interest rate for the countries concerned. The only countries that are doing poorly in the eu at the moment are Spain, Greece, Ireland and Italy, most of the rest are experiencing greater economic growth than the british isles but you hear bugger all about that.
As I said if anyone can present a well reasoned argument as to why the uk would be better off out, I'll concede the point. No one has.
Also why is the euro 'weak' at the moment ? Who says it's 'weak' ? In 2006 it was 1.69 euros to the pound, that is weak, at the moment it's 1.24, last year it was 1 pound to 1 euro and I remember the british press bleating because it was too strong. Jesus.
