"So much for those who say we would not be better out of this mess ? "
You really don't get it do you youngmafbog?
There is no simple way out of the mess for anyone. If Greece falls the Euro falls, if the Euro falls, the banks fall, if the banks fall, the world falls. It doesn't matter a jot whether the UK is part of the Euro-zone, part of the EU, or part of neither. The global economy is in dire straits, and you seem to be under the impression that all you need to do is pull up the drawbridge and somehow the UK will be the only country in the world that will escape the consequences.
