The Euro is a currency, the EU is a political and economic organisation. It's ludicrous to suggest that the same arguments would work for both, they are not the same thing.
They are both outlined in the same treaty. They are suppose to go together hand in glove.
If you had no money at all and I had a massive stack of cash, do you think it unreasonable that I should give you some of that cash to get you back on your feet? If not, are you campaigning against paying any tax?
Would that be a loan? You did say give which implies not.
If this is one of the principles of the EU then go tell it to Germany! They didn't
give to Greece but laid them up with more debt, debt they can never pay back because they don't have the means to. And only 5% of this loan actually goes to the Greeks the rest does a lap of honour to the banks. Germany showed its true colours; the 4th Reich is blossoming well, and it is the colours of red in tooth and claw; dog eat dog; the true nature of man, of tribal loyalties and adherences to a god of ideology to the nth degree.
I'm afraid, Jeremy, your high ideals and the EU are poles apart.
