I always find this rabbit attitude to the Euro odd. I am back and forth to Ireland all the time. As it is well known they have had their problems. It is simplistic to say that the inability to control their interested rates led to a flood of cheap money, that was used in the construction boom and then bust. Inept goverment/regulators that ignored the warnings, and were even complicit in trying to bury the consequences (https://en.wikipedia.org/wiki/Anglo_...ns_controversy) was the number one cause of the crash. No credible person in ireland would blame the Euro/propose leaving. If the Euro is such a disaster why is that?
Greece is another example. Anti Euro people say the Euro stops them devaluing. Not sure if many economists would say that devaluing is a credible way of fixing an inheriently broken economy. Do you blame the Euro for highlighting that the Greek economy is broken? It's a bit like shooting the messenger.
