Twenty-First Century Inequality & Capitalism: Piketty, Marx and Beyond is a collection that begins with economist Thomas Piketty’s 2014 book. Most chapters critique Piketty from the perspective of critical theory, global political economy or public sociology, drawing on the work of Karl Marx or the Marxist tradition. The emphasis focuses on elements that are under-theorized or omitted entirely from the economists’ analysis. This includes the importance of considering class and labor dynamics, the recent rise of finance capitalism, insights from feminism, demography, and conflict studies, the Frankfurt School, the world market and the world-system, the rise of a transnational capitalist class, the coming environmental catastrophe, etc. Our goal is to fully understand and suggest action to address today’s capitalist inequality crisis.
