Portugal is in trouble, so is Italy. The upcoming Italian banking center crisis, which is pretty much inevitable, will reset any economic gains from the last 5 years quite nicely. France is doing okay-ish. Definitely second fiddle to Germany though.
Speaking of Germany. Their bone-headed fear of - gasp - inflation and austerity measures are dividing Europe, not to mention Merkel's idiotic handling of the refugee crisis. Euro-scepticism is growing. Fully 1/3 of Germans are now Euro-sceptics. Let that sink in for a moment. Right-wing nationalism is increasing. Marie Le Pen and Geert Wilders are growing in popularity. If that's not a failure of Euro-liberal policies, I don't know what is.
I don't think what happened yesterday is great. But portraying the EU experiment (I call it that since it still might fail) as some kind of giant happy family and the UK being the unhappy, ungrateful child is grossly inaccurate.
The EU project has been in trouble and under pressure for a while now. I'm 100% convinced this is only the first domino to fall.
