Personally, i think that the immigration issue is a red herring. All countries can benefit by importing the skills that can't be met internally. Let's face it, on the numismatic front we can go back to the Short Cross coinage of Henry II when Philip Aimer of Tours was brought over to cut the new coinage. J P Droz, Mestrelle, the Roettiers etc. were all brought in to do a job, so immigrants are nothing new - we need them. We just need to be selective. Australia, Canada, the US and many others keep strict controls on immigration, we should be no different
 
	The crux of the issue is that all countries want to be masters of their own destiny, even those that are committed to the EU, which is why there is no clarion call for a politically unified Europe and ultimately that is why it must fail as a project. It can only work if all the countries pull in the same direction without regard to their sovereign interests. Ain't gonna happen.
