Despite the seismic shifts of Brexit and President Trump, the editors find that the trend lines of social change that Therborn observed in the aftermath of the financial crisis of 2008 remain visible. On the one hand, austerity measures and neoliberal politics continue to increase inequality and erode the welfare state, and authoritarianism, nationalism, racism and xenophobia and right-wing extremism remain on the rise. On the other hand, social movements are resisting these developments, and rebellious citizens are demanding political change. In the Trump era, the book’s overarching idea—that the maturation of a new generation of critical thinkers and activists represents a fertile source of progressive social change—gives cause for hope. In light of the key difference between the two transformational strategies that have been the focus of this book—interstitial and symbiotic—the main insights and lessons of the contributions are summarised.
