The most powerful illusion of bourgeois economics is its claim to be value-free. Open any introductory textbook and you will find a discipline that presents itself as a neutral science of scarcity, choice, and efficient allocation—as if the laws it describes were as immutable as the laws of physics. Yet this very claim to neutrality is the first clue that we are dealing with ideology. A science that genuinely described material reality would not need to insist so loudly on its own objectivity; it would let its predictive power speak for itself. The paradox at the heart of mainstream economics is that its formalism, mathematical rigor, and pretense to scientific method serve not to reveal the truth about capitalist production but to conceal it—to transform historically specific relations of exploitation into eternal features of human nature.

The Marginal Revolution Erased Class from Economic Theory

Before the 1870s, political economy still asked the questions that mattered: where does value come from, and how is it distributed between workers, capitalists, and landlords? Adam Smith and David Ricardo had identified labor as the source of all value, and while their analyses were incomplete and often contradictory, they at least recognized that class conflict was at the heart of production. Karl Marx developed this labor theory of value into a full critique of political economy, demonstrating that profit arises from the exploitation of workers—from the difference between the value workers produce and the value they receive as wages.

Then came the marginal revolution. In the 1870s, William Stanley Jevons in England, Carl Menger in Austria, and Léon Walras in Switzerland independently developed a new theory of value based not on labor but on subjective utility—on the marginal satisfaction a consumer derives from the last unit of a good. This was a brilliant ideological maneuver. By shifting the source of value from production to exchange, from labor to subjective preference, the marginalists eliminated the working class from economic theory at the very moment when the industrial proletariat was organizing into trade unions and socialist parties across Europe. If value is determined by individual preferences in the marketplace, then there is no exploitation, no surplus value, no class antagonism—only free individuals exchanging goods to mutual benefit.

Walras made the political intention explicit. He wrote that his general equilibrium theory would "render futile" the socialist critique of capitalism by proving mathematically that competitive markets achieve optimal outcomes. The mathematics was elegant, but the assumptions were absurd: perfect information, no transaction costs, all producers and consumers too small to affect prices, and all preferences given prior to exchange. These assumptions were not simplifications for analytical convenience; they were ideological erasures of the very features that define capitalism: the concentration of ownership in the means of production, the compulsion of workers to sell their labor power, the anarchy of market competition, and the periodic crises that devastate working-class communities.

The marginal revolution did not merely replace one theory with another. It reconstituted the object of economic inquiry itself. Classical political economy had asked: how does this system produce and distribute wealth, and what are the conflicts inherent in that process? Neoclassical economics asks: how do individuals allocate scarce resources among competing ends? The first question centers class; the second centers the isolated individual. The first leads to critique; the second leads to apology.

GDP Measures Capital's Health, Not Society's

Consider the most widely reported economic statistic in the world: Gross Domestic Product. GDP is presented as a measure of economic well-being, a proxy for whether a society is thriving or floundering. Politicians rise and fall based on whether GDP is growing or shrinking. Central banks calibrate interest rates to keep GDP on a stable trajectory. Yet GDP was explicitly designed during World War II to measure the productive capacity of the American war economy—not to measure human welfare, not to capture distribution, not to tell us anything about whether workers are better off.

Simon Kuznets, the economist who developed the modern GDP accounting framework, warned in his 1934 report to Congress that "the welfare of a nation can scarcely be inferred from a measure of national income." His warning was ignored. Today, GDP includes as positive additions the cleanup costs of environmental disasters, the medical expenses of treating occupational diseases, the construction of prisons, and the financial services that extract fees from working-class households. It does not count unpaid domestic labor—the work overwhelmingly performed by women that reproduces the labor force every day. It does not deduct the depletion of natural resources or the destruction of ecosystems. It treats the extension of the working day and the intensification of labor as pure gains, with no recognition that these represent attacks on the physical and mental health of the working class.

The abstraction of GDP is not a scientific limitation—it is a political choice that directs our attention away from the concrete realities of working-class life.

The material consequence of this abstraction is stark. Since 1973, US GDP has grown by more than 300 percent in real terms. Over the same period, real median wages have risen by barely 15 percent, and most of that growth occurred in the late 1990s. The entire increase in national output has been captured by the capitalist class—by those who own the means of production, not by those who operate them. What GDP registers as growth, the working class experiences as stagnation: longer hours, more debt, greater precarity, the collapse of social services, the destruction of unions. The statistic that politicians call "growth" is, from the standpoint of labor, simply the rate at which capital accumulates value extracted from the working class.

The Phillips Curve Treats Unemployment as a Policy Tool Against Workers

Perhaps no concept better reveals the class content of mainstream economics than the Phillips Curve—the supposed trade-off between inflation and unemployment. In its original 1958 formulation, A.W. Phillips observed an empirical correlation between low unemployment and rising wages in the United Kingdom. By the 1970s, Milton Friedman and Edmund Phelps had transformed this observation into a theoretical claim: there exists a "natural rate of unemployment"—the NAIRU, or Non-Accelerating Inflation Rate of Unemployment—below which inflation will accelerate uncontrollably.

"There is always a temporary trade-off between inflation and unemployment; there is no permanent trade-off. The temporary trade-off comes not from inflation per se, but from unanticipated inflation." — Milton Friedman, 1967 Presidential Address to the American Economic Association

Friedman's theory, for which he won the Nobel Memorial Prize in Economic Sciences in 1976, was a direct weapon against the working class. The "natural rate" is not natural at all. It is the level of unemployment necessary to keep workers from gaining sufficient bargaining power to demand higher wages. Whenever unemployment falls, workers can quit bad jobs, demand raises, or organize collectively. Wages rise. This is, from the standpoint of workers, called progress. From the standpoint of capital, it is called inflation, and it must be stopped by raising interest rates, throwing people out of work, and restoring the reserve army of labor to its proper size.

The empirical evidence for NAIRU has always been weak. The theory predicts that unemployment below the "natural rate" will cause accelerating inflation. Yet in the late 1990s, US unemployment fell below 4 percent—far below any plausible estimate of NAIRU—while inflation remained stable. Mainstream economists did not abandon the theory. They simply revised their estimates of the natural rate downward, admitting no crisis of confidence. When the theory fails, it is the world that is wrong, not the theory. This is the hallmark of ideology: a framework that is systematically insulated from falsification by its own assumptions.

The Phillips Curve, in its modern form, is not a description of reality. It is a policy manual for central bankers telling them when to inflict unemployment on the working class. The "natural rate" is the unemployment rate that capital requires to maintain its power over labor. Mainstream economics has simply naturalized this requirement, treating the reserve army of labor as a technical parameter rather than a relation of class power.

Rational Actor Models Naturalize What Capitalism Produces

The core microeconomic model—the perfectly rational, self-interested actor making optimal decisions at the margin—is presented as a description of human nature. It is nothing of the sort. The "economic man" (and the gendering is deliberate, for this abstraction is masculine in its assumptions) is not an anthropological universal but a specific historical product. Capitalism is the first mode of production in which labor power is routinely bought and sold as a commodity, in which individuals are formally free to enter contracts, and in which social reproduction depends on market exchange. The rational actor model takes these historically specific conditions and projects them backward and forward as transhistorical features of human existence.

Friedrich Engels, writing in 1845, observed that "political economy came into being as a natural result of the expansion of trade, and with it there developed, in place of the simple, unscientific foresight of the merchant, a whole system of permitted fraud, a complete science of enrichment." The rational actor model is the mature form of this science: a mathematical apparatus that derives "optimal" outcomes from assumptions that already encode the priorities of capital. The actor has no class position, no history, no social relations—only preferences, endowments, and constraints. The problem of production is reduced to the problem of exchange. The extraction of surplus value disappears into the analysis of supply and demand.

The steel-man defense of this approach—the strongest version of the empiricist counter-argument—is that economics simply models observed behavior without ideological content. Just as physics models the trajectory of a falling object without judging gravity, so economics models consumer choices, firm behavior, and market outcomes without taking sides. The models are tools, not political statements. When they fail to predict, they are revised.

Yet this defense collapses upon examination. Physics does not tell falling objects that they should fall. Economics tells unemployed workers that they are not trying hard enough to find jobs. Physics does not claim that its model of friction is a description of how the world ought to be. Economics claims that competitive markets produce efficient outcomes—an explicit normative claim smuggled inside a positive framework. The very separation of "positive" from "normative" economics, codified by Friedman in his 1953 essay "The Methodology of Positive Economics," is itself an ideological move that immunizes the discipline against critique. If economics describes what is, and what is happens to be capitalism, then capitalism is simply reality to which we must adapt—not a historically specific system that could be otherwise.

The rational actor model does not describe how all humans behave. It describes how humans are trained to behave under capitalism. The competitive individualism, the instrumental calculation, the treatment of social relationships as transactions—these are not innate features of human nature but learned responses to a system that punishes cooperation and rewards predation. Neoclassical economics mistakes the pathology of capitalism for the essence of humanity. It then uses this mistake to argue that any alternative to capitalism is "unrealistic" because it violates "human nature."

Ideology operates not through the denial of reality but through the naturalization of the particular. Mainstream economics is ideology in its purest form: a system of thought that takes the historically specific relations of capitalist production—wage labor, commodity exchange, the drive for accumulation—and presents them as the inevitable expression of rational choice under conditions of scarcity. Its mathematical formalism gives it the appearance of scientific objectivity. Its refusal to examine the class content of its own categories gives it the function of apologetics.

The working class does not need better economics. It needs a different science: a political economy that begins not from the isolated individual but from the social relations of production, not from exchange but from labor, not from equilibrium but from contradiction. The project of Marxist political economy is to rip away the veil of neutrality and reveal the class struggle at the heart of every economic category—wages, prices, profit, rent, interest, growth. This is not a call to reject rigor for rhetoric. It is a call to build a science adequate to its object: a capitalism that is not eternal, not natural, and not rational, but contradictory, crisis-ridden, and ultimately, replaceable.

The mathematics of neoclassical equilibrium becomes a symphony playing in a burning theater—elegant, precise, and utterly indifferent to the fire consuming the audience.
