Sunkara presents a compelling argument for democratic socialism as a solution to the deep economic and social inequalities of contemporary capitalism. He traces the history of socialist movements, exploring both their successes and failures, and offers a vision for a modern, pragmatic socialism rooted in mass participation, strong welfare systems, and a democratic control of key industries. Rejecting both authoritarianism and neoliberalism, Sunkara calls for a revitalised left that builds power through political organising, labour movements, and electoral engagement to create a more just and equitable society.
