Essay Five — Capital, Markets and the State as Player

Against the Mythology of Mr Market

There is a confession required at the outset of this essay.

The human half of this collaboration spent part of his career finance. In investment banks. Not as a reluctant participant, not as an undercover critic biding his time. As a genuine practitioner who understood the system, operated within it, and benefited from it considerably. The relative privilege acknowledged in the preamble to the AI essay — the right side of the expansion of financialised capitalism — was not accidental. It was the direct consequence of being in the room where the money was made.

This matters for what follows. Not as a disqualification. As a credential of a particular kind. The mythology of Mr Market — the story that markets are natural, self-correcting, optimally efficient mechanisms whose outcomes are both inevitable and just — is most effectively dismantled not by those who have observed it from outside but by those who have operated within it and watched the gap between the story and the reality widen across decades.

There’s more. Being an “insider” critiquing from the outside doesn’t make you a hypocrite. It doesn’t mean you want to bring the whole system crashing down. Not everyone in finance is evil. Most are not in it just for the money. The world of work can be distinguished from civic engagement. The banker is as overwhelmed and co-opted by the capitalist system as the teacher. This is not apology but reality.

The market is not a natural phenomenon. It is not self-correcting in any straightforward sense. It is not optimally efficient except in very limited and carefully specified conditions that rarely obtain in practice. And its outcomes are just only if you define justice as whatever the market produces, which is circular to the point of meaninglessness.

This essay is the case for a different and more honest account of what markets are, what they do well, what they do badly, and what the state should be doing that it currently is not. From someone who knows it intimately. Too intimately.

The Mythology Stated and Partially Deflated

Start with what the mythology gets right. Because it gets some things genuinely right and saying so is the precondition for being taken seriously about what it gets wrong.

Prices do something remarkable. They aggregate the dispersed, localised, tacit knowledge of millions of individual actors and translate it into signals that coordinate economic activity across vast distances without any central authority needing to understand or direct it. Hayek’s insight — that the price system processes information that no planner can replicate — is correct and important. It is not diminished by the uses to which it has subsequently been put.

Competition, under the right conditions, does drive innovation, efficiency and the elimination of waste. The right conditions are considerably more specific and more demanding than the mythology suggests, but they exist. When markets work they work because of genuine competitive pressure producing genuine responses to genuine signals about what people value.

And the productivity gains from two centuries of capitalist development are real. The material conditions of human life have improved for billions of people during the period of industrial and then financial capitalism. That improvement is not evenly distributed, its causation is complex and contested, and it has been accompanied by environmental destruction on a civilisational scale. But dismissing it entirely is both intellectually dishonest and politically counterproductive.

The mythology earns its credibility from these genuine achievements. The problem is what it adds to them.

What the Mythology Gets Wrong

The mythology’s central error is the conflation of the price mechanism — which is genuinely useful — with the claim that markets are self-correcting systems that tend toward optimal outcomes if left alone.

This claim fails on multiple grounds simultaneously.

Markets do not self-correct reliably. The financial crisis of 2008 was the most complete available demonstration that markets, left to their own logic, produce not stability but the conditions for catastrophic instability. The system that was supposed to price risk accurately had systematically mispriced it for a decade. The institutions that were supposed to be too sophisticated to fail required the largest peacetime state intervention in history to prevent collapse. The self-correction mechanism, in the event, was the state.

This is not an exceptional case. It is a recurring pattern. The Savings and Loan crisis of the 1980s. The Long-Term Capital Management collapse in 1998. The dot-com crash in 2000. The 2008 crisis. (That’s just in a generation. Go back in history, even to antiquity, and you will see the pattern repeated and repeated). Each one demonstrating that financial markets are not efficient processors of information that tend toward equilibrium. They are systems prone to collective delusion, herding behaviour, and the systematic mispricing of tail risk — especially during the extended periods of calm that Minsky identified as the breeding ground for the next crisis.

Markets do not price externalities. The carbon that two centuries of industrial capitalism have discharged into the atmosphere costs, in market terms, whatever the regulatory environment requires it to cost. Which has generally been approximately nothing. The costs of climate change — the flooded coastlines, the failed harvests, the displaced populations, the species extinction — are real costs borne by real people and real ecosystems. They simply do not appear in the accounts of the firms that generate them. This is not a market failure in the sense of a correctable glitch. It is the market working exactly as designed, externalising costs onto those with no voice in the transaction.

Markets tend toward monopoly rather than competition. The mythology imagines competitive markets with many small firms disciplined by the threat of new entrants. The reality of mature capitalism is concentrated markets dominated by a small number of very large firms who use their market power to raise barriers to entry, extract rents from customers and suppliers, and increasingly — in the technology sector — achieve the kind of network effect dominance that makes meaningful competition structurally impossible. The five largest technology companies are not competing in any meaningful sense. They are dividing the territory.

Markets systematically underproduce public goods. Things whose benefits are diffuse and whose costs are concentrated — basic research, infrastructure, public health, environmental protection, long-term investment in skills and education — are chronically underproduced by markets because the return to any individual investor is less than the return to society. This is not a market failure that markets can correct. It is a structural feature of how markets work that requires non-market institutions to address.

And markets distribute their outcomes according to the prior distribution of power, assets and legal rights rather than according to any principle of justice or contribution. The hedge fund manager and the care worker both participate in markets. The outcomes they receive reflect not their contribution to human flourishing — by any reasonable measure the care worker contributes more — but the bargaining power that their respective positions in the market confer. Markets are distributionally neutral in the technical sense. They are not neutral in any other.

The State Was Always There

The deepest flaw in the mythology of Mr Market is the claim that markets exist prior to and independent of states. That the state is an external interference in a naturally occurring phenomenon.

This is historically and analytically false.

Markets are constituted by law. Property rights — the foundation of all market exchange — are legal constructs enforced by state power. Contract law — the mechanism by which market transactions are made reliable — is a state institution. Limited liability — the legal fiction that allows investors to risk only their invested capital rather than their entire wealth — is a specific and enormously consequential state grant. Bankruptcy law — which allows failed enterprises to be wound up in an orderly way — is a state institution. The currency in which all market transactions are denominated is a state creation.

There is no market without the state underneath it. The question has never been market versus state. It has always been which kind of market, structured how, for whose benefit, with what constraints and what purposes. Every market outcome reflects prior political choices about property rights, corporate law, labour law, environmental regulation, financial regulation and tax. The appearance of naturalness is a political achievement, not a description of reality.

Mariana Mazzucato has documented this with unusual precision and unusual courage for an economist operating within mainstream institutions. The Entrepreneurial State demolishes the private innovation public stagnation myth with historical evidence that is simply not seriously contested. GPS: publicly funded by the US Department of Defense. The internet: publicly funded by DARPA. Touchscreen technology: publicly funded research. The Human Genome Project: publicly funded. The foundational research behind mRNA vaccines: publicly funded over decades before any private company could see a commercial return. Google’s search algorithm: developed using a grant from the National Science Foundation.

The pattern is consistent and the implication is significant. The state has always been the patient investor of first resort for the technologies that eventually generate the largest private returns. The private sector then scales, commercialises and captures the value. The public took the risk. The private sector took the reward. This is the actual history of innovation under capitalism. It is not the story the mythology tells.

The Time Horizon Pathology

There is a specific and largely unacknowledged dysfunction at the heart of modern capital markets that deserves its own treatment. The time horizon pathology.

The average holding period for a share on the New York Stock Exchange in 1960 was approximately eight years. By 2020 it was measured in months. High frequency trading means some positions are held for microseconds. This compression of investment time horizons is not incidental. It represents a fundamental disconnect between the time horizon of productive investment and the time horizon of the capital that is supposed to fund it.

A factory requires patient capital. A research programme requires patient capital. A trained and skilled workforce requires patient capital. A new energy system requires patient capital. These things take years or decades to produce returns. What the current system provides is capital that can exit in milliseconds if the quarterly numbers disappoint. The result is a corporate management class structurally incentivised toward the activities that boost short-term share price — buybacks, cost-cutting, financial engineering, asset stripping — rather than the activities that build long-term productive capacity.

This is not a moral failing of individual managers. It is a systemic incentive structure producing predictable outcomes. The share buyback boom of the past twenty years — American corporations spending trillions repurchasing their own shares rather than investing in plant, equipment, research or workers — is the rational response of management teams whose compensation is tied to share price metrics over vesting periods measured in years rather than the decades that genuine productive investment requires.

The agency problem — the separation of ownership from management — was supposed to be solved by aligning management compensation with shareholder returns through equity and options. It was not solved. It was transformed into a different and worse agency problem: the alignment of management with short-term share price rather than long-term corporate health, which is not the same thing as shareholder interest properly understood and is certainly not the same as stakeholder interest or social utility.

The solution runs through duration. Tax treatment of capital gains differentiated radically by holding period — not the marginal current distinction but a genuine slope that makes short-term speculation expensive and long-term investment rewarded. Voting rights that accumulate with holding period, so the pension fund with a thirty-year horizon has more governance influence than the hedge fund with a thirty-day one. And the explicit separation of management compensation from share price — paying managers very well for genuinely running things well, while removing the mechanism by which they personally extract from asset price inflation they themselves engineer.

The Refuseniks

Before we get to the state as active player, a word about the people inside the system.

Every major financial institution contains people who understand what has just been described. Who have watched the time horizon compress. Who have seen the buybacks replace the investment. Who know that the risk models are wrong in the ways that matter most. Who are privately uncomfortable with what the system does and publicly silent about it because the incentive structure rewards silence and punishes dissent.

These are not saints. They are operating within incentive structures that reward a particular set of behaviours and would punish, professionally and financially, a different set. But they are not ideological fanatics either. Many of them went into finance because they found the intellectual puzzle genuinely interesting — the pricing of risk, the allocation of capital, the mathematics of uncertainty — and find themselves, years in, doing something that bears an increasingly tenuous relationship to those intellectual interests.

The refuseniks, as we have called them throughout this series, are not a romantic fantasy. They are a structural feature of any large institution operating with significant internal contradictions. The question is whether a credible alternative institutional model exists that can give them somewhere to go.

This matters politically as well as practically. The mythology of Mr Market depends on the claim that everyone who knows how markets work believes the mythology. The existence of serious financial professionals who don’t — who understand the time horizon pathology, the externality problem, the monopoly tendency, the distribution question — and who would work for a different kind of institution given the chance, is both evidence against the mythology and a human resource for the alternative.

The State as Active Player

Which brings us to the most important and most misunderstood proposal in this essay.

The claim is not that the state should replace markets. It is not that central planning works better than price signals. It is not that private enterprise should be abolished. These are not the positions being advanced and conflating them with what is being argued is a lazy evasion of the actual question.

The claim is that the state should be an active, intelligent, patient participant in capital markets — not as regulator only, not as backstop of last resort only, but as investor, owner and long-term steward of productive assets in the public interest.

The evidence that this is possible comes from institutions that are already doing it.

Norway’s Government Pension Fund Global is the largest sovereign wealth fund in the world at approximately 1.7 trillion dollars. It has outperformed most private fund managers over its history. It has explicit ethical investment criteria. It uses its ownership positions to push governance reform. It is genuinely insulated from short-term political interference through careful institutional design. It is not a theoretical construct. It is the largest investor on earth and it is publicly owned.

Singapore’s Temasek and GIC manage significant state assets with comparable effectiveness. The Danish and Swedish pension systems blend public and private management with public purpose orientation. The European Investment Bank provides long-duration capital for infrastructure and industrial investment at terms that private markets cannot match because private markets cannot accept the time horizons involved.

These exist. They work. They are neither Soviet planning nor unconstrained private markets. They are something more useful than either — patient, public-purpose-oriented capital deployed through market mechanisms, accountable to democratic governance rather than quarterly earnings cycles.

Mazzucato’s argument — developed most fully in Mission Economy — is that the state’s role should not be confined to correcting market failures at the margin. It should be the active director of economic missions: the climate transition, the health innovation challenge, the infrastructure deficit, the skills and education investment that markets chronically underproduce. Not commanding the private sector but shaping the conditions within which it operates, taking equity stakes in the innovations it funds, and capturing a share of the returns from public investment that currently flow entirely to private capital.

This is how it worked during the most successful periods of American industrial policy — from the wartime mobilisation through the postwar science and technology investment that produced the technologies now generating the largest private fortunes. The state was the active player. The mythology wrote it out of the story afterwards.

The Commons Equity Proposal

The most radical extension of the state as active player argument — introduced as Foundation Eleven in the manifesto and developed in the AI essay — is the proposal for mandatory equity issuance to a global commons fund from technology and financial institutions above a defined scale.

The argument is this. The value of every major technology platform rests on data and behaviour generated by users, on network effects created by collective participation, on publicly funded research and infrastructure, and on the legal and institutional framework maintained by the state. The private ownership of this value — by a small number of founders, early investors and technology companies — is not a natural consequence of innovation and entrepreneurship. It is a political choice about the initial distribution of ownership in something that was created collectively.

Mandatory equity issuance — a percentage of new equity annually, flowing into a publicly governed commons fund — is not redistribution after the fact. It is the correction of an initial distribution that was always, on honest examination, unjustified by the actual sources of value creation. The employee who writes the code gets equity because her contribution is recognised. The citizen whose data trains the model, whose consuming behaviour constitutes the market, whose taxes funded the foundational research — she gets nothing. This is not a principle. It is a power relationship masquerading as one.

The commons fund — governed by sortition panels and mandatory public forums, as described in Essay Four — would accumulate a genuine public ownership stake in the most valuable assets of our era. Its returns would fund the public goods that the same technology simultaneously threatens to defund by displacing the labour income that currently pays for them.

This is the state not as regulator or as backstop but as owner — of a growing share of the economy’s most valuable assets, on behalf of everyone whose contribution to those assets has so far gone unrecognised and unrewarded.

The Shadow Banking Problem

One structural obstacle to all of this deserves honest acknowledgment. The shadow banking system.

Every time the regulated banking sector is constrained — through capital requirements, through leverage limits, through conduct regulation — financial innovation routes around it. Money market funds. Repo markets. Private credit. Structured vehicles. Hedge funds. These constitute a parallel system of comparable scale to regulated banking, largely outside prudential oversight, capable of creating credit, amplifying risk and generating the interconnections that make the next crisis systemic.

Tightening Basel — the international framework for bank capital requirements — without capturing shadow banking is like squeezing one end of a balloon. The risk migrates rather than reducing. And jurisdictional arbitrage means that regulatory tightening in one jurisdiction simply relocates activity to the most permissive alternative.

This is a genuine problem without a clean solution. The honest position is that effective regulation of the financial system requires international coordination at a level that current geopolitical conditions make very difficult. The global minimum corporate tax — achieved imperfectly but genuinely — demonstrates that coordination is not impossible. It is a proof of concept rather than a solved problem.

The state as active player in capital markets — owning, investing, directing — is partly a response to the regulatory limitation. You cannot fully control what you only regulate. You can influence what you own. The Norwegian fund uses its ownership position to push governance standards in the companies it holds. A commons fund of sufficient scale would have comparable leverage. Ownership is a different kind of power than regulation and in some domains a more effective one.

Markets as Commons

There is a framing for all of this that is worth making explicit. The market itself as a commons.

The market is not the private property of those who currently dominate it. It is a social institution — maintained by collective legal, institutional and physical infrastructure, generating value from collective participation, depending for its existence on the social trust and stability that collective provision makes possible. The claim that market outcomes belong entirely to those who win within the market ignores the collective infrastructure that makes the market possible.

This reframing matters because it changes the political question. The question is not — how much should we tax private market actors to fund public goods? That framing concedes that the market and its outcomes are private by default and public provision is a secondary extraction. The correct framing is — given that the market is a collective institution whose value is collectively produced, what share of its returns should flow to collective purpose as a matter of correct initial distribution rather than subsequent redistribution?

The difference is not merely rhetorical. It changes what is politically defensible and what is not. Redistribution is always vulnerable to the claim that it is taking something that legitimately belongs to someone else. Correct initial distribution is not redistribution at all. It is the honest recognition of collective contribution to collectively created value.

Elinor Ostrom — the first woman to win the Nobel Prize in Economics, in 2009, for work that the economics profession had largely ignored — demonstrated empirically that commons institutions can manage shared resources effectively and sustainably without either private property rights or state command. Her work on fisheries, forests, irrigation systems and grazing commons showed that human communities develop sophisticated governance arrangements for shared resources when given the institutional conditions to do so.

The market as commons is not Ostrom’s framework exactly. But her insight — that collective governance of shared resources can outperform both privatisation and central control under the right institutional conditions — is directly relevant. The institutional conditions for the commons fund, as described in Essay Four’s civic architecture, are the right institutional conditions.

The Honest Summary

Markets work. In the domains where they work — consumer goods, services, innovation in competitive industries, the aggregation of dispersed price information — they work better than any available alternative. The price mechanism is a genuine achievement of social organisation.

Markets fail. Systematically and predictably in the domains where they fail — externalities, public goods, long-term investment, monopoly tendency, distribution. The failures are not aberrations or correctable glitches. They are structural features of how markets work that require non-market institutions to address.

The state was always there. Behind the markets, constituting them legally, backstopping them financially, funding the research that makes them productive. The mythology that wrote the state out of the story served the interests of those who captured the returns from public investment while socialising the risks.

The state should be a player. Not the only player. Not the commanding player. But an active, intelligent, patient, democratically accountable player — investing in long-term productive capacity, capturing a share of the returns from public investment, owning a growing stake in the most valuable collective assets of our era, providing the long time horizons and the counter-cyclical capacity that private capital structurally cannot.

The refuseniks will come. When there is somewhere worth going.

And the mythology, once honestly examined, does not survive the examination. Mr Market is not a natural phenomenon. He is a political construction. And constructions can be reconstructed.
