The Ghost in the Utility Function

Human motivation is a complex and often contradictory force. We are, at once, creatures of base material need and seekers of transcendent meaning. We are individuals who prize autonomy, yet we are fundamentally social animals, incapable of forming a sense of self without the mirror of others. In the vast architecture of economic thought, theories have been built to explain how we satisfy our material needs—how we produce, consume, and exchange. However, a ghost haunts this machinery. It is the invisible, yet ever-present, engine of social status: the innate, relative, and often non-material human drive for rank, respect, and recognition.

This drive for status is arguably a primary mover of economic life, as powerful as the desire for material wealth itself. It dictates not just what we wish to consume but why. It shapes our choice of career, our patterns of saving, the education we pursue, and the ways we signal our virtue. Yet, for most of the 20th century, our dominant socioeconomic theories—the grand models of capitalism, socialism, and libertarianism—were constructed with this critical piece missing. This omission was not a simple oversight. It was a foundational blind spot, a necessary exclusion to make the models function.

The innate drive for status is, in short, analytically inconvenient. It fits neatly into none of the dominant paradigms. For neoclassical economics, which built elegant mathematical models of individual, rational choice, status is a disruptive and "messy" variable. Its value is not absolute but relative—my utility depends on your consumption—and its origin is not an independent individual preference but a social consensus. For Marxist and social democratic theory, which prize collective action based on objective economic class, status is a divisive and subjective force. It threatens to pit individuals within the same class against each other, obscuring the primary, unified conflict between labor and capital. For libertarianism, which prizes the autonomous individual as its philosophical core, status is a strongly normative force that shapes our preferences and compels our behavior, calling into question the very possibility of a truly autonomous actor.

Each of the "big three" ideologies was forced, by its own foundational logic, to ignore, mischaracterize, or dismiss the status engine. This chapter will conduct a two-part exploration. First, it will diagnose this shared failing, examining the blind spot at the heart of neoclassical, Marxist, and libertarian thought. Second, it will synthesize the new generation of economic thinking—from behavioral economics, contest theory, and identity economics—that is finally bringing the ghost into the machine, providing a more robust and realistic model of human motivation by placing status and identity back at the center of economic analysis.

The Veblenian Critique: The Status Seeking Homo economicus

The blind spot of mainstream neoclassical economics originates with its central protagonist: Homo economicus, or the "economic man". This theoretical model portrays humans as agents who are "consistently rational and narrowly self-interested," and who pursue their subjectively defined ends optimally. First defined in the 19th century by thinkers like John Stuart Mill, this idealized human was said to behave rationally and make decisions "solely based on self-interest, without the influence of emotions or irrational impulses". In the 20th century, this model became the bedrock of microeconomics, which observes production and consumption as driven by a supply and demand model. This entire framework rests on the hypothetical maximization of utility by income-constrained individuals.

The first and most potent critique of this new orthodoxy came from the institutional economist Thorstein Veblen, a merciless detractor of the theories of his time. In 1900, Veblen castigated the discipline for turning the individual into a "lightning calculator of pleasures and pains, who oscillates like a homogeneous globule" [1]. Veblen's fundamental criticism was that neoclassical economics possessed an "utterly nonhistorical and simplistic view of human nature and social institutions". By attempting to explain all human behavior in terms of "rational, egoistical, maximizing behavior," Veblen insisted, the theory "explained nothing".

Veblen’s counter-proposal was that the primary engine of economic life was not the maximization of material utility but the competition for social rank. He argued that production and consumption are "social and cultural phenomenon". In his 1899 work, The Theory of the Leisure Class, Veblen argued that social status, once earned by prowess, had in modern society become earned and displayed by "patterns of consumption". He introduced the concepts of "conspicuous consumption" and "conspicuous leisure"—the demonstrable waste of time and money—as the primary mechanisms for signaling status. For Veblen, economic life was defined by "invidious distinctions of wealth" and a "powerful and ceaseless motivation" of "emulation of those who have more".

This behavior is not irrational, as some critics suggest; rather, it is a different form of rationality. It is the perfectly rational signaling and display of social rank. The neoclassical model, however, is structurally incapable of understanding it. In Veblen's view, people are "caught on the pattern of emulative consumption," which leads to "chronic dissatisfaction" because "it was always possible to imagine, and want, more". This directly contradicts the neoclassical concept of utility maximization, which implies a state of satisfied equilibrium.

Defenders of the neoclassical model have long argued that Veblen's critique, and others like it, attack a "straw man" [2]. The argument is that the model of Homo economicus is more flexible than critics admit. The rationality implied in the model "does not restrict what sort of preferences are admissible". An agent's utility function, these defenders claim, could be "linked to the perceived utility of other agents," making the model "compatible with other models such as Homo reciprocans, which emphasizes human cooperation". In this view, a desire for status can simply be written into the utility function as another "taste" or "preference" to be maximized, alongside apples and oranges.

This technical "patch," however, only serves to reveal the deeper flaw in the model. Treating status as just another "good" to be consumed fundamentally misunderstands its nature. The utility derived from a private good, like an apple, is independent of what others consume. The utility derived from a status good—an exclusive club membership, a rare painting, a position in a hierarchy—is entirely dependent on others not having it. It is primarily a relative, rivalrous rank rather than an absolute, widely expandable good.

The neoclassical model, rooted in what is known as methodological individualism, is designed to aggregate the absolute gains in utility of discrete individuals. It is structurally ill-equipped to model a preference whose primary utility is relative and whose origin is socially constructed. Sociologists have long pointed out that the Homo economicus model "ignores the origins of tastes and the parameters of the utility function by social influences". Veblen's critique was not that people have an innate "taste for status," but rather that the "historically changing phenomena" and "social mores" of a pecuniary culture shape their tastes. Some individuals internalize these preferences from their social hierarchy—their desires are endogenous to the group—while others, often elites and cultural innovators, actively create and define these status markers, exercising genuine individual choice that then cascades downward as emulation by the majority.

The Class Prison of Marxists and Social Democrats

If the neoclassical blind spot is an obsession with the individual at the expense of the social, the Marxist blind spot is its perfect inverse. This framework, which forms the ideological backbone of traditional socialist and social democratic thought, sees only the collective social structure and is blind to the individual's drive for status within it.

The foundation of this worldview is historical materialism [3]. This theory, developed by Karl Marx and Friedrich Engels, "seeks the ultimate cause and the great moving power of all important historic events in the economic development of society". For Marx, history is defined by the "changes in the modes of production and exchange" and the "consequent division of society into distinct classes, and in the struggles of these classes against one another". All of human motivation, in this model, is reduced to one's objective class interest. Society is polarized into two groups: the bourgeoisie (owners) and the proletariat (workers). The end-point of this struggle is the development of "class consciousness"—a shared awareness of exploitation that will trigger a revolution.

The primary critique of this model is that it is "too rigid" in its economic determinism. It presents individuals as "puppets of economic forces," underestimating the role of "free will and cultural complexity". The theory "underestimates how much individuals and groups can resist, adapt, or create change outside of purely economic pressures". By focusing so intensely on social class, traditional Marxism overlooks other vital, and often competing, forms of identity and hierarchy, such as gender, race, and culture.

This rigidity creates a massive conceptual problem. What happens when individuals do not act according to their "objective" class interest? The theory's only mechanism for explaining this discrepancy is the concept of "false consciousness". This concept, derived from Marxist theory, "refers to the systematic misrepresentation of dominant social relations in the consciousness of subordinate classes". Members of the underclass, it is argued, suffer from "distortions, errors, and blind spots" that "systematically conceal or obscure the realities of subordination".

Here, the blind spot for status is fully revealed. If an individual worker prioritizes individual status—seeking prestige within their community, adhering to cultural or religious norms, or competing with their neighbors for rank—over collective class solidarity, the theory has no language for this except to label it "false consciousness." It cannot conceive of status-seeking as a parallel, legitimate, and powerful human motivation. It is blind to all non-economic, non-class-based forms of hierarchy. The Frankfurt School of critical theory, which sought to develop Marxist studies, later attempted to synthesize Marx with psychoanalysis to explain the "turbulent political factionalism and reactionary politics" (like Nazism) that 20th-century Marxism was unable to explain. They saw that mass culture itself could "mask the 'surplus repression' that shapes human instincts and needs in line with the functional requirements of social domination", but the core problem remained.

This purely theoretical failing has now resulted in a profound political crisis for modern social democracy. For decades, social democratic parties, which are built on a foundation of working-class economic interests, have been facing a "crisis of support" [4] from their traditional base. This phenomenon is the ultimate empirical proof of the Marxist blind spot.
