"The Accumulation of Capital" by Rosa Luxemburg is a book published in 1913. Luxemburg challenges Marx's theories by arguing that capitalism cannot survive in isolation. She contends that the system requires constant access to non-capitalist markets to realize surplus value and continue expanding. This need drives imperialist conquest of pre-capitalist regions. Luxemburg controversially predicts that once capitalism dominates the entire globe, its internal contradictions will cause inevitable collapse. The work sparked fierce debate within the socialist movement. (This is an automatically generated summary.)
