At the core of Karl Marx’s revolutionary ideas is his conception of the working class as the “gravedigger” of capitalism. Driven to collective resistance by exploitation and oppression, working class struggle holds the potential to challenge and overcome instilled divisions and develop a universal outlook directed towards human need, not profit for the few. The Communist Manifestoconcludes with a momentous call for workers of all countries to unite! Today, the global working class is larger and more powerful than ever before, with nothing to lose but its chains and a world to win.
