How can we understand social democracy today? This ambitious book offers a global perspective on the nature of capitalism; its past and future possibilities of survival; the differentiation between neoliberal, authoritarian and social democratic systems, exemplified by the United States, China, and the EU; and the conflict relationships between them. Reflecting on urgent global risks, such as climate change, pandemics and nuclear confrontation - Mouzelis & Sotiropoulos explore why these risks can only be dealt with by the cooperation of these three major players in the global arena. They explore how the model of social democracy, which in the previous century tamed unfettered capitalism in some national contexts, can help contain the excesses of global capitalism now. In clear, compelling and coherent terms, the authors demonstrate how unchecked antagonism among these three major players has the potential to spill-over into inertia or reluctance to manage these urgent risks, to the detriment of humanity as a whole.
