The political economy founded by Karl Marx remains the key to understanding the capitalist economic system. David Harvey has been writing about and teaching "Capital" by Karl Marx for over 40 years. His legendary video courses make Marx's main work accessible to a wider audience even in the 21st century. Based on his lectures and methodically following his successful introduction to the first volume of "Capital," Harvey now guides readers through the second volume. His aim is to provide even first-time readers with a deeper entry into this fascinating, yet long-neglected work. While the first volume focuses on the production process of capital, this volume primarily addresses the realization of surplus value through the buying and selling of commodities.
