What of the EU subsidies that under-wrote a good deal of that much admired economic growth? What part did that play?
Quite a lot but there's also the low Corporation Tax which a blind EU eye was turned to. It meant a lot of company headquarters moved there which could as easily move elsewhere. Microsoft has a large establishment there, but I'm sure it's pretty much low tech stuff, packaging up software.
Having said that, I wouldn't dismiss it all as an EU wheeze and a bubble. I don't think their educational system has been degraded the way ours has and there's a confidence there which didn't exist before.
