The growing polarization between the rich and powerful and the poor and powerless, the yawning social and developmental divide and the multidimensional systemic crisis of capitalism have given rise to a fundamental problem of our times: barbarism or socialism? Will we continue on the path of capitalist barbarism or move to a more just socialist system? Bringing together a group of passionate socialists, 21st Century Socialism participates in the emerging and critical debate concerned with reinventing and rebuilding socialism. Revisiting concepts of class and capital, reinventing Marx, problematizing party politics, re-examining alternative forms of socialist politics and learning lessons from Venezuela's Bolivarian Revolution, 21st Century Socialism explores how socialism needs to be re-imagined to make it relevant to 21st-century.
