You are to captured by your ideology. It does not really matter what you personally think about. The thing is that the EU has completely failed as a union to provide the economic growth we need and has no plan on how to address this. We are completely export dependent (about 50% of GDP, meaning any world economic crisis will cause massive unemployment and fiscal crisis) and our internal market has withered and the purchasing power is plummeting.

China is going to do what China does but it's economy is in tatters something you would probably know if you actually looked at what is happening with their economy. Combine that with the same demographic crisis as EU and you have another country that might have already hit it's economical peak. The leadership is showing no ability to create an internal market and is busy stomping out any dissent internally as economical reality sets in and people loose jobs and their future. Unless their turn their economy around creating an internal market any international economic crisis will collapse their export oriented economy.

I don't know why you think everything is so bleak. Yes, Europe is inter-connected to the world. We export a lot and we import a lot. Unemployment in Europe has been not been terrible for a long time.

Of course there is room for improvement and there are political challenges, for instance to enact the pension reforms needed for the demographic changes but Europe has achieved also a lot we can be proud of. Without Europe and without the single market, we would be facing the same issues Britain is facing: Being too small, unable to regulate anything on their own, dependent on foreign trade partners, etc.
