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.
