The Cerberus Market

 

Commodity, Broker, Consumer: Marx, Keynes, and Smith on AI Capitalism

The economic problem is simple enough to state plainly: if capitalism weakens the consumer, who is left to buy? AI capitalism promises cheaper production, more automation, and more productivity. But capitalism does not run on production alone. It runs on production that can be sold. Someone must have money, freedom, and reason to buy what the system produces.

That is where the contradiction starts. A company can cut labor costs and improve its margins. But wages are also demand. If many companies automate work, weaken bargaining power, and concentrate income, the system may become better at producing and worse at selling. It becomes a beautiful machine with a shrinking customer base.

The same problem appears in platform and AI markets. People are not only buyers. They are also data sources, training material, behavioral signals, unpaid evaluators, and dependent users. The market is not merely selling to them. It is built through them.

The system wants people cheap as workers, rich as consumers, transparent as data sources, dependent as users, and creative as training material. Those demands cannot all be satisfied forever.

The Role Confusion

There is an inherited absurdity in being commodity, broker, and consumer at once, because those roles are supposed to be structurally separate. A commodity is sold. A broker mediates the sale. A consumer buys.

Cerberus works because the three heads share one body. Commodity, broker, and consumer are supposed to be separate market roles because they have different interests. In AI capitalism, they are fused into one subject. The result is not clever integration but structural impracticality: one body is asked to be the value extracted, the mechanism of circulation, and the buyer charged for access.

You are the commodity because your behavior, attention, language, preferences, social graph, and future likelihoods are packaged as value.

You are the broker because your clicks, prompts, shares, corrections, ratings, posts, and interactions help route, train, validate, and refine the system. You are not merely being sold; you are helping organize the conditions of the sale.

You are the consumer because you pay for access, products, subscriptions, recommendations, visibility, productivity tools, identity services, and sometimes even privacy from the same systems extracting from you.

This is more than unfairness. It creates economic confusion. If the person is input, market signal, buyer, and disposable cost all at once, the system has trouble knowing what the person is for. It wants to extract from the person and sell to the person at the same time. That can work for a while. It cannot work cleanly forever.

Marx: The Contradiction Inside Capital

Marx helps because he understood capitalism as a system that creates contradictions from within. Capital wants to reduce labor costs, increase productivity, expand markets, and accumulate profit. But labor is not only a cost. Workers are also consumers, social beings, and the human base through which production is reproduced.

This is the contradiction AI sharpens. Capital wants labor minimized at the point of production and maximized at the point of consumption. It wants fewer workers to pay, but enough consumers to buy. Each firm may rationally automate and cut costs. But if many firms do it at scale, the wage base erodes. The individual capitalist behaves rationally; the system becomes collectively irrational. It is the old contradiction wearing better software.

Marx would also notice enclosure. Shared human knowledge, language, code, art, behavior, and social intelligence become raw material for privately owned systems. The collective output of human culture is turned into proprietary capability. Then that capability is sold back as access. This is not land enclosure in the old form, but it has the same structure: a commons becomes private revenue.

The alienation also mutates. In industrial capitalism, the worker is separated from the product of labor. In AI capitalism, people are separated from patterns of their own lives, expressions, and intelligence, which return as proprietary services, rankings, recommendations, scores, and tools.

Keynes: The Demand Problem

Keynes would ask the blunt question: who has the money to buy what the economy can produce? If productivity rises while purchasing power concentrates, the economy can produce more than ordinary people can afford to consume. That is not abundance. It is imbalance.

The rich do not consume in the same proportion as ordinary households. A dollar shifted from wages to profits does not automatically return as broad demand. It may become savings, asset speculation, share buybacks, monopoly expansion, or investment in further labor displacement.

This is the bakery problem: a bakery that can make infinite bread in a town where everybody is celiac is technically impressive and economically useless. The issue is not whether the bakery is productive. The issue is whether its output can be absorbed.

A Keynesian rescue would require political management of AI productivity gains: redistribution, public investment, shorter working hours, income supports, stronger automatic stabilizers, and institutions that keep productivity gains from concentrating entirely at the top. The technical question is demand. The social question is whether automation becomes shared freedom or private rent.

Adam Smith: The Moral Conditions of Markets

Adam Smith can be rescued, but only if we rescue the real Smith, not the cartoon version. Smith was not simply saying greed magically saves society. His economics sits beside a moral theory of sympathy, justice, prudence, trust, and social judgment. Markets require more than self-interest. They require conditions under which exchange is not domination dressed as choice.

Smith was suspicious of monopolies, collusion, rent-seeking, and merchants who capture public policy for private advantage. He understood that business interests often prefer restriction over open competition. He did not think concentrated commercial power automatically serves the public good.

From a Smithian perspective, platform and AI capitalism are suspect because they distort the conditions of free exchange. A market is not truly free when users cannot understand the bargain, avoid the infrastructure, inspect how visibility is priced, contest data extraction, or negotiate with the systems that mediate their work and social life.

This is where the moral dimension matters. Not Victorian respectability, exactly. Smith belongs to the Scottish Enlightenment, shaped by a Protestant moral world in which sympathy, restraint, justice, and social judgment still mattered. A market with the handshake removed and the fine print promoted to king is not a purified market. It is a predatory one.

Remove Smith’s moral compass from Smith’s economics, and the market becomes a logistics system with no conscience. The mistake is not returning to Adam Smith; the mistake is returning to a mutilated Smith, a Smith stripped of sympathy, justice, and suspicion of commercial power.

The market has something of the old maritime trade route in it: cargo, brokers, ledgers, risk, ports, insurance, and respectable distance from harm. The point is not to flatten historical differences, but to notice the recurring form: human life converted into transferable value, moved through an infrastructure of intermediaries, and morally laundered as commerce. In that register, the person is cargo, navigator, and passenger at once: helping steer the ship, paying for the voyage, and still getting marched onto the plank when margins demand it.

The Disappearing Economic Agent

Modern economics often begins with the rational economic agent, but this premise depends on social conditions the model usually treats as background: trust, information, autonomy, stable institutions, enforceable contracts, and meaningful alternatives.

If capitalism corrodes those conditions, the agent at the center of economic theory disappears. What remains is not a free chooser but a managed subject inside private and public infrastructures. At that point, even production is no longer guaranteed, because production itself depends on coordination, skill, trust, demand, and social reproduction.

Smith’s moral dimension is not decorative. It is part of the market’s operating system. Without it, the rational agent disappears; exchange degrades; demand weakens; productivity loses meaning; and capital becomes control over decaying assets.

When Productivity Loses Its Market

The productivity problem is not only that productivity may fall. The deeper issue is that productivity can lose its ordinary capitalist meaning. In capitalism, productivity matters because more output can become more value. But that only works if output can be sold. Without demand, productivity becomes capacity without realization.

Productivity without demand is a factory on an island, getting more efficient at producing goods no ship comes to collect. The machines may be excellent. The output may be enormous. But the market circuit is broken.

Here productivity needs to be understood in its oldest and most basic sense: the capacity to produce more output with less labor, time, land, energy, or material. That meaning has been with us since the agricultural revolution. But under capitalism, productivity must also pass through the market. It becomes economically meaningful not only when more can be produced, but when that output can be sold, financed, or otherwise absorbed as value.

This is the Hegelian shape of the problem, later sharpened by Marx: the contradiction is not external to the system. It grows from inside it. The same logic that pushes capital to automate labor, weaken wages, and concentrate ownership also weakens the consumer base that makes productivity profitable. Put less politely: even in Gucci shoes, shooting yourself in the foot still hurts.

If the mass consumer weakens, the old civilizational meaning of productivity does not disappear. But its ordinary capitalist channel breaks. Producing more with less is still technically powerful; it is just no longer enough to sustain a consumer market. Capital then looks for projects large enough to absorb capacity and justify investment: defense, energy infrastructure, climate adaptation, data centers, compute expansion, logistics, resource control, administrative automation, elite health, or other megaprojects. Space colonization is the cartoon endpoint of this logic; the nearer versions wear hard hats, uniforms, lab coats, and procurement badges.

This changes the question. The market no longer asks only, who buys the product? It asks, what project can absorb capital, machinery, labor, and legitimacy? When the checkout line disappears, capital starts looking for a construction site.

That is why this is not ordinary consumer capitalism. Productivity becomes less consumer-facing and more project-facing. It serves states, corporations, infrastructure owners, security systems, and elite markets. The public may still be involved, but less as a strong consumer and more as a managed population inside the project.

Three Diagnoses, One Crisis

Marx, Keynes, and Smith point to different parts of the same crisis. Marx says the system undermines its own social base. Keynes says it threatens effective demand. Smith says it corrupts the moral and competitive conditions that make markets legitimate.

Put together, the diagnosis is sharp: AI capitalism may produce too efficiently for a society whose income, autonomy, and moral foundations it has eroded. The problem is not that the system cannot produce enough. The problem is that it may damage the people, institutions, and markets that make production meaningful.

Who Will Buy?

The likely answer is stratification. Wealthy individuals buy premium agency: better AI, better health, better education, better privacy, better security, better lawyers, and better insulation from the systems others must inhabit. Firms buy automation to reduce labor dependence. States buy AI for administration, surveillance, defense, welfare management, policing, and public service automation. Ordinary people receive cheaper, degraded, subsidized, ad-supported, behavior-extractive versions.

So the market may not disappear. It may mutate. The old mass consumer becomes less central. Corporations, states, and wealthy households become the most solvent consumers. Everyone else becomes a managed user base: economically weaker, behaviorally legible, technologically dependent, and still valuable as data, attention, compliance, and political population.

The mall does not vanish; it becomes a members-only logistics hub with a public waiting room. That is the drift from consumer capitalism toward rentier-control capitalism. The system earns less by selling abundant goods to a broadly prosperous public and more by charging access, controlling infrastructure, extracting data, licensing intelligence, managing risk, and selling tools of optimization to those who can pay.

If there is any Smithian hope here, it is not that markets fix themselves. It is that markets can be made legitimate, and kept from becoming self-defeating, only when they are held inside moral and institutional limits: fair competition, public goods, real alternatives, restraints on monopoly, and a social world in which people can still act as agents rather than managed inputs.

Smith does not rescue the system by blessing self-interest. He rescues the question by reminding us that commerce without moral conditions is not freedom; it is organized dependency.

The consumer problem is where Marx's contradiction, Keynes's demand failure, and Smith's moral test meet. Not a pleasant room, but a very clear one.
