Conflict of Economic Theories: Marx vs. Marginalism
📌 The conflict centers on a salary dispute where Jorge (workers' representative) uses Karl Marx's theory to argue that high profits result from exploitation of labor and that total income should belong to the workers.
🏛️ Luis (owner) rejects Marx, advocating for Marginalist thought as the superior, contemporary economic theory, claiming Marx's views are obsolete.
📉 Classical and Marxist economists viewed political economy as a social science studying production and distribution relations between social classes (workers, capitalists, landowners).

The Emergence of Marginalism
💡 Marginalism arose in the late 19th century, during the Second Industrial Revolution, as a response to Marxist criticism regarding wealth inequality.
🌍 Key pioneers include Leon Walras, Stanley Evans, and Karl Megger, with Alfred Marshall systematizing the school around 1890 in his *Principles of Economy*.
🚫 This school, also called neoclassical, sought to break from classical thought by eliminating analysis of social conflict, exploitation, and reducing the field to just "economy," omitting "political."

Marginalist Conception of Economic Science
👤 Marginalists focus on the individual (social atoms) rather than social groups; the working class as a unit is disregarded.
🧠 Economic processes are explained via the psychological mechanisms of agents, encapsulated by the concept of Homo Economicus.
⚖️ The central economic problem is maximizing pleasure/satisfying needs with minimum effort, leading to universal laws applicable across time and place due to scarcity (unlimited needs vs. scarce resources).
🧪 Marginalists employ mathematics and models derived from physics/chemistry, aiming for ideological neutrality and optimal solutions.

The Subjective Theory of Value and Utility
🔄 Classical economics determined value based on production costs (objective value); marginalists introduced the subjective theory of value.
💵 Value is determined at the moment of exchange based on the consumer's judgment of utility.
💧 The price of goods is set by scarcity and marginal utility (the utility of the last portion consumed), not total utility (e.g., water vs. diamonds).

Income Distribution Under Marginalism
🤝 Marginalists assert that production factors (work, land, capital) are sold on the market like any other good, and their prices (salaries, earnings) are determined by supply and demand.
⚖️ The equilibrium salary equals what the worker contributes to production; income distribution is fair as everyone receives according to their contribution.
🚫 They oppose state intervention and unions, viewing the free, competitive market as the mechanism for achieving maximum consumer well-being and balancing income distribution.
📉 Unemployment is attributed to forces attacking free competition, like unions or legislation preventing salary reductions.

Critique and Lasting Influence
🏭 The marginalist system has profoundly influenced modern economics, making the market the great organizer of economic activity, assuming markets tend toward perfect competition without intervention.
👨‍🔧 Workers found the marginalist premise unrealistic, as they cannot freely choose their working hours; they decided to organize to assert their claims through collective action.

Key Points & Insights
➡️ Luis argues that a worker's salary should be discussed individually, based on the market's determination of what they contribute to production.
➡️ The subjective theory of value shifts value determination from production costs to the consumer's perception of marginal utility.
➡️ Marginalists believe unemployment is caused by limiting the free fluctuation of salaries through unions or legislation, not by market dynamics themselves.
➡️ Workers rejected the marginalist view of individual choice and opted for collective organization to negotiate work conditions and salaries.
