Visionary ideals, realpolitik and regulatory overkill, common culture and identity, and finally “Brexit” – it is in these terms that we commonly perceive and discuss Europe. Our debates are all about what is ideally and ideologically desirable, about what is politically and administratively feasible, and about who we are in cultural and historical terms. Important though all of this may be, these debates tend to disregard Europe’s inner mechanism: the economic workings that make Europe actually move. Economic activity – including the “common market” and the Euro – not only secures Europe’s relative wealth as well as its political and societal stability, it also constitutes the core that holds Europe together. While visions and cultural memories may sometimes fade, while political cohesion and institutions may crumble, it is economic activity – and the structures and processes that have grown out of the cooperation of economic players – that facilitated the ideas and politics of European unity in the first place."
