Book excerpt: Twenty-first-century capitalism has little more to offer than a menu of despair: pandemics, deepening inequality, worsening depression, runaway climate change, intensifying authoritarianism and escalating militarism. Twilight Capitalism offers a wide-ranging analysis of the origins, implications and scope of the “combined” social crisis of 2020 and beyond. A compelling case is made that Karl Marx’s critical analysis of capitalism, along with his program of class-struggle socialism, is essential to understanding and addressing the most important social, economic and ecological problems of our time.
