There is nothing recent about Ireland doing well out of the EEC , we have been members since 1973, you might also note that in 1963, and 1967 Britian had its application refused to join the EEC.
Comparing Ireland to Wales , now that is a joke, Ireland has the fastest growing economy in Western Europe, another very real reason why Ireland has done so well recently,unlike Wales.
In addition to this, Irish people would be very proud of their neturality.
As Irish citizens, we know none of our taxes paid goes towards wars, in other parts of of the world.
Spain has done very well out of the UK, buts thats down to people travelling there and spending currency.
As far as Brussels fleecing the UK is concerned, when you guys join the Euro, and it will happen sooner rather than later, as the UK will be unable to continue to trade competively with the transperancy Euro brings.
Another reason why Ireland prospers,
Why for example would I buy something in the UK, change my Euro to Sterling, pay a transction cost at the counter of my Bank Branch, on top of the cost of the goods I am purchasing, when I could simply do a Euro to Euro transfer in a Sister European country, even if I wanted to buy in the UK, its not viable any more.
Ireland hasnt declared herself netural, it has been netural since its foundation as a free State in 1921.
