The article compares the views of Walras and Marx on labor exchange. Walras sees labor as a simple service, while Marx emphasizes the worker's choice and constraints in their work. Marx's perspective challenges the neoclassical idea that labor conditions are solely determined by market forces, suggesting that socio-political factors play a crucial role. This highlights the importance of recognizing the worker's agency in shaping labor conditions, rather than viewing labor as a commodity like any other.
