**Wage-Labour and Capital & Value, Price, and Profit** by Karl Marx is a compelling introduction to Marxist economic theory, combining two of his most influential works. In *Wage-Labour and Capital*, Marx explores the relationship between labor and capital, illuminating how the commodification of labor under capitalism generates profit for capitalists at the expense of workers. In *Value, Price, and Profit*, Marx delves deeper into the mechanisms of capitalist economies, discussing the labor theory of value, the creation of surplus value, and the inherent exploitation of wage labor. Together, these texts offer a powerful critique of capitalism's structure and dynamics, providing readers with foundational insights into Marxist economics and the social implications of labor exploitation. This edition is an essential resource for anyone seeking to understand the theories that have shaped modern political and economic thought.
