The Marxist theory of capitalist growth and transformation has often been shrouded in obscurity, either by endless recapitulation of Marx's texts or by excessive use of mathematical formalism. This short book presents an integrated and rigorous view of capitalist development - technical change, class relations, trends in the profit rate and share, cyclical and long-term crisis - in a form that is accessible to serious readers with or without prior training in economics or familiarity with Marxist thought.
