Is capitalism entering its terminal phase? Despite the fact that the question of the "definitive crisis" of this socioeconomic system has been recurring at all the decisive moments of the long 20th century (Great War of 1914, crisis of 1929, World War II, crisis of the 1970s), after which capitalism has been able to mutate to subsequently trigger even more formidable and complex crisis scenarios than in the previous case, the answer offered in this book is emphatically affirmative. The crisis trends currently detected (debt crisis, banking and financial crisis, democracy crisis, ecological crisis and geopolitical crisis) approach, in Streeck's opinion, limits that are difficult to overcome in the current reproduction framework of really existing capitalism. As this book shows, since the 1970s it has entered a path of stagnation marked by a succession of financial crises associated with short periods of growth, which have led to the systemic crisis that started in 2007 and which, far from being reabsorbed with Ease continues to consistently erode growth prospects and democratic political responses to a new paradigm of understanding and managing economic and financial activity. The profitability crisis has resulted in an increase in the oligarchic redistribution of income and wealth, and this in growing structural inequality, which seriously undermines democratic systems and imposes highly authoritarian modes of political management. As a consequence of all this, democratic capitalism, pushed by its internal contradictions and in the absence of an antagonistic political subject similar to the one that the labor movement once represented, seems to have entered a spiral of decomposition, against which the only alternative it consists of "buying time" on the part of the ruling classes and elites, who are blindly committed to the unequivocal reconstruction of the current model of exploitation and privilege. If this analysis is shared, the task of criticism and politics of the new anti-systemic movements is no longer to advocate partial solutions or to elaborate schemes for an impossible reform, but to boldly opt for construction, in the environment of created systemic chaos by current economic and political elites, from a genuinely post-capitalist horizon.
