Europe is living its Weimar moment. The historic task of the European Union (EU) today, the book argues, is to articulate and institute a new imaginary of prosperity. Imaginaries of prosperity integrate societies around the shared pursuit of a prosperous future, while rendering “political-economic” questions the main preoccupation of politics. The new imaginary of prosperity today has to be both credible (able to provide answers to contemporary challenges) and appealing (conjuring a world in which people want to live). It has to include not only an alternative macroeconomic framework (a different role for tax, public spending, or welfare provision) but also a different set of microeconomic institutions (a new role for the corporation, technology, industry, finance, and consumption). It is exactly in this latter space that the EU has undertaken the first important steps towards reimagining prosperity. The book analyses several policy fields, showing that the EU has already made significant efforts to foster more caring consumption, circular products and technologies, sustainable industry, and fairer corporate activity. But the EU has to go further and faster – if it intends to respond effectively to the soaring problems, while halting another Europe’s slide into tribalism.

Chapter 2 provides a theoretical framework for the book. I articulate, first, why it is useful to think in terms of social imaginaries, rather than alternative sociological concepts (such as paradigms or ideologies), for analysing social integration in modern societies. I then explore why, in modernity, it was imaginaries of prosperity that provided the most stable foundations for social integration. These imaginaries can bridge, I argue, the plurality of worldviews and identities, while at the same time play into modernity’s strengths, namely democracy and knowledge governance. However, any particular imaginary of prosperity can provide only a temporary foundation, because it will sooner or later produce too many problems and contradictions to continue fulfilling its integrative role. When such problems mount, imaginaries of prosperity become subject to their own dialectics, having to shift eventually between privatised and collective routes to prosperity. If, however, the pressures for change cannot be institutionalised through democratic channels, we have seen in the past – and are seeing again today – that illiberal and undemocratic tribal imaginaries may take hold, making identity (rather than prosperity) the main vector of politics.
