Value, Price, and Profit (1865) is a foundational work by Karl Marx, presented as a lecture to the General Council of the First International, addressing debates about wages and their impact on capitalist production. In it, Marx critiques the notion that workers' demands for higher wages harm the economy, instead arguing that the real issue lies in the exploitation of surplus value by capitalists. He provides a concise explanation of labor value theory, surplus value, and the dynamics of profit, while advocating for workers to engage in class struggle to ultimately abolish the wage system and capitalism itself.
