We need to get out of the EU asap. The Greek default might be the tinder that sparks the fire. Nations can trade without pillocks in Brussels telling them how to do it,and sucking on the gravy train in the meantime.
The EU is a vast, wallowing, monster which has outgrown itself to an extent that nobody trusts it anymore.
Uk is friends with the trading world - do we need the EU interfering with this? Telling us what we can & can't do? Moreover, limiting our own government legislation & powers? Treaties we have signed up to - and for what? Who asked the general public first?
Cameron - if he has any testicles, needs to either radically alter the EU, or accept that it's just a money sapping monster.
I can't see him doing that - he might get an appeasement of miniscule proportions which he will no doubt gloat emphatically about prior to the vote/referendum.
As I see it,manufacturers work together, which is good. Do we need the EU for that? No.
Immigration- I think we are stretched to the limit on that one (I'm not racist, but someone will disagree).
My conclusion - GO GREECE!! And the best of luck
