Like the Tea Party maintains for the US, the EU is not a transfer union. Citizens in key countries have not signed up for a union in which social services in one country are funded by citizens of another. Whereas in the US this pivots around shared health care, in Europe it is about the Euro itself and its failure to create a common market for labour as well, like it has in the US.
The EU project is vital to Europe. Only 70 years ago nations defined themselves by seeking each others demise. The Nazi’s grabbed power in Germany with an agenda of fear and hatred that resonated deeply with the Germans. Fear and hatred again are powerful motivators but this time no other nations are recipient: the institutions of the EU themselves stand exposed. To rescue Europe we must slow it down, admit that many measures were implemented against common sense and against the will of the Europeans often directly so. (The French and Dutch remember the referendum, constitution and Lisbon treaty all too well).
An increased dose of euroscepticism would be healthy for the EU: the parliament as it is now is too far removed from and far too easily dismisses the sentiments that are current in many member states. But it would be best if euroscepticism were to be more widely embraced by mainstream parties rather than by extremist ones who propose to derail or leave the EU and/or Euro.
