Ireland, Nilsen. Currently we are 'suffering' full employment, immigration and a still (just) growing economy, lowish taxes. Mainly because the country is run essentially on the British/American model. Something which many other countries in Europe would do well to follow. The Euro hasn't exactly damaged the Irish economy. The only real negative aspect of the Euro was the fact that people like Doctor, Dentists, hairdressers and other service providers etc racked up their prices shortly after the changeover. Otherwise it has been mostly positive. The other positive aspect to me is as the Euro increases in value against the dollar, my subcription to AH gets lower every month!
Personally I feel that most of the anti Euro debate is spurious. Despite all the doom mongering the changeover worked quite well. Issues like a federal government etc are just red herrings. No one is ready for that idea right now in the Euro zone or not.
