The Price of Equality: Milton Friedman and the Economics of Good Intentions
By Matthew Parish
Wednesday 21 October 2026
One of the most entertaining characteristics of the American economist Milton Friedman was his capacity to reduce the most elaborate political philosophies to a few sentences of devastating simplicity. Whereas other economists might fill entire books with equations explaining the economic consequences of government intervention, Friedman preferred to identify the essential absurdity of a proposition and then leave his audience to contemplate the wreckage. His observations were frequently provocative, sometimes unfair and occasionally exaggerated. Nevertheless they possessed a quality rare amongst economists: ordinary people could understand them.
Consider his famous observation that when a society seeks equality, A and B decide what C should do for D, while taking a commission along the way. The proposition is almost childishly straightforward. A and B are politicians, bureaucrats or other people who exercise political authority. C is the individual whose resources are being appropriated. D is the supposedly deserving beneficiary of their benevolence. The commission is the portion of C’s resources that disappears into the administrative and political machinery supposedly designed to improve D’s circumstances.
Friedman articulated this argument in a lecture entitled The Role of Government in a Free Society, delivered at the Hoover Institution at Stanford University on 9 February 1978. The surviving transcript uses slightly different wording from the familiar quotation, but its meaning is unmistakable. Friedman was arguing that attempts to enforce economic equality necessarily involve the concentration of coercive power in the hands of people who do not themselves bear the full consequences of their decisions.
The argument is attractive because it exposes an uncomfortable feature of political morality. It is remarkably easy to be generous with somebody else’s money. A politician can announce a programme to assist the poor, acquire considerable public admiration for his compassion and then send the bill to taxpayers who may never have supported the programme in the first place. The politician is rewarded for his intentions, the bureaucracy is rewarded for administering them and the taxpayer is expected to regard his contribution as a moral duty.
However Friedman was making a more sophisticated argument than merely complaining that governments are expensive or that politicians are hypocrites. Behind his rhetorical flourish lies one of the most important concepts in modern economic theory: deadweight loss. It is a concept that explains why an apparently harmless transfer of wealth from one person to another may leave society as a whole poorer, even where nobody steals anything and the government spends every penny it collects.
Understanding deadweight loss requires us to distinguish between the redistribution of existing wealth and the destruction of opportunities to create new wealth. This distinction is fundamental to understanding why well-intentioned economic policies can produce consequences quite different from those their authors anticipate.
The strange arithmetic of economic redistribution
Imagine a government announces that wealthy citizens must contribute an additional £1 billion annually to help the poor. At first sight the economic consequences appear straightforward. The wealthy lose £1 billion and the poor gain £1 billion. The total quantity of money in society remains unchanged. The government has simply moved it from one set of pockets into another, presumably on the grounds that the latter have a greater need for it.
Economists call this a transfer. A transfer does not, by itself, destroy wealth. Indeed there may be powerful moral and economic arguments in favour of it. A pound transferred from a millionaire to a pensioner who cannot afford heating may do considerably more good than the same pound would have done remaining in the millionaire’s bank account. This reflects what economists call the diminishing marginal utility of income: the more money one already possesses, the less additional satisfaction one is generally likely to derive from receiving another pound.
However the arithmetic becomes more complicated when we consider how that £1 billion is collected and distributed. The government must employ tax collectors, accountants, inspectors, administrators, lawyers and officials to manage the programme. It must develop eligibility criteria, establish procedures for assessing applications, investigate fraud and resolve disputes. All these activities consume real economic resources, including labour and capital, which might otherwise have been used to produce goods and services.
This is Friedman’s commission, or at least its most obvious manifestation. Yet there is something else, less immediately visible, that may be considerably more important. The collection of taxes and distribution of benefits change people’s incentives to engage in economic activity. Certain transactions that would otherwise have occurred cease to take place altogether. Businesses that might have expanded decide not to do so. Employees who might have worked additional hours conclude that the financial rewards are insufficient to justify the effort.
The resulting economic loss cannot be measured merely by counting the money that government officials receive in salaries or spend on computers. It consists of economic opportunities that have disappeared altogether. To understand its significance, we must undertake a short excursion into the elementary principles of economics.
What is deadweight loss?
Suppose a tradesman in Lviv is prepared to undertake a small repair job for €90. This sum covers his materials, the value of his time and the effort involved. A customer needs precisely this repair and would be prepared to pay as much as €120 for it. They agree upon a price of €100, both parties are satisfied and a mutually beneficial exchange takes place.
The economic value created by the transaction amounts to €30. The customer receives a service worth €120 to him, while the tradesman incurs costs that he values at €90. The difference represents the combined economic benefit to the two participants. Economists call this economic surplus, and it is one of the fundamental measures of how markets generate prosperity.
Now imagine that the government introduces a €40 tax upon this particular repair service. The tradesman must receive at least €90 after tax to make the transaction worthwhile, so he must charge at least €130. But the customer is unwilling to pay more than €120. The transaction therefore never occurs.
What has happened to the €30 of economic value that would otherwise have been created? It has disappeared. The customer does not receive his repair, the tradesman does not undertake the work and the government collects precisely nothing because there is no transaction to tax.
That missing €30 is an example of deadweight loss.
The crucial distinction is that the government has not taken €30 from one person and given it to another. The €30 was never created at all. Nobody possesses it, nobody spends it and nobody benefits from it. It has vanished as a consequence of a government policy that prevented two willing participants from completing a mutually advantageous exchange.
In technical economic terminology, deadweight loss is the reduction in total economic surplus resulting from a distortion that prevents resources from being allocated to their most valuable uses. Taxation is one possible source of such distortions, but it is by no means the only one. Monopolies, subsidies, price controls, trade restrictions and various forms of regulation can all create deadweight losses under particular circumstances.
The International Monetary Fund explains the same principle in terms of taxation driving a wedge between what purchasers pay and what sellers receive. The resulting reduction in mutually beneficial transactions constitutes an economic cost additional to the revenue actually transferred to government.
The invisible losses
The significance of this phenomenon is that deadweight loss is largely invisible. When a government increases taxation, accountants can calculate how much additional revenue the treasury collects. Economists can estimate the amount of money transferred to welfare recipients, the cost of administering the programme and the salaries paid to the officials responsible for its implementation.
What is much harder to measure is the economic activity that never takes place. How many restaurants were never opened because their prospective owners concluded that the taxes and regulatory burdens made the investment unattractive? How many employees were never hired because the additional costs of employing them exceeded the economic value they could create? How many entrepreneurs decided against developing an innovative product because the potential financial rewards did not justify the risks?
There are no invoices for the restaurant that was never opened. There are no employment contracts for the workers never hired, and there are no financial statements for the company that never existed. Yet the economic consequences of these absences may be immense. They represent an invisible diminution of society’s productive capacity that conventional political debate frequently ignores.
This is one reason why economists distinguish between the average rate of taxation and the marginal rate. An average tax rate describes the proportion of a person’s total income surrendered to the government. The marginal tax rate describes how much tax is paid upon the next pound earned. It is the latter figure that frequently influences decisions about whether to work additional hours, undertake a second job or pursue a new commercial opportunity.
Suppose a self-employed professional discovers that, after taxation, only 40 pence of every additional pound earned will remain in his pocket. He may reasonably conclude that an additional evening’s work is not worth sacrificing time with his family. Nobody need accuse him of laziness or irresponsibility. He is simply responding rationally to a change in the balance between effort and reward.
If the value of the additional output would have exceeded the genuine economic cost of producing it, the loss of that activity represents deadweight loss. The government does not necessarily collect additional revenue because the work is never undertaken. Society loses the benefit of production that would otherwise have occurred.
An analogous problem can arise at the receiving end of redistribution. A person who receives means-tested benefits may lose some of those benefits as earnings increase. If an additional £100 of earnings produces £20 of income tax and a £60 reduction in benefits, that person retains only £20. The effective marginal deduction rate is 80 per cent, even though the formal income tax rate is only 20 per cent.
The problem here is not that people receiving social assistance are unwilling to work. It is that policy may create circumstances in which working additional hours brings remarkably little financial benefit. A compassionate programme designed to protect vulnerable people can inadvertently make their economic independence more difficult to achieve.
Why a little taxation may be very different from a great deal
The size of deadweight loss depends substantially upon how strongly people alter their behaviour in response to changing prices and incentives. Economists describe this responsiveness using the concept of elasticity. Some activities are relatively insensitive to financial incentives, while others are highly responsive.
People must purchase certain basic necessities almost regardless of their price, whereas demand for luxury products may fall rapidly when prices increase. Similarly, some workers have considerable flexibility over their working hours or investment decisions, while others have very little. Taxation imposed upon highly responsive economic activities is generally more likely to change behaviour and thereby create substantial deadweight losses.
There is another important feature of the conventional economic analysis. Under familiar simplifying assumptions, the deadweight loss generated by a tax increases approximately with the square of the tax rate. Doubling a tax from a low initial level can therefore produce roughly four times the deadweight loss, provided the relevant supply and demand relationships remain approximately unchanged.
This is not a universal mathematical law of government finance. Real economies are considerably more complicated than the simple models economists use to illustrate these principles. Nevertheless the underlying lesson is important: successive increases in taxation may become progressively more economically damaging as people find stronger reasons to alter their behaviour.
It follows that governments cannot necessarily increase their revenue indefinitely by increasing tax rates. Beyond some point, higher rates may provoke sufficient changes in employment, investment, consumption or tax compliance to undermine the anticipated revenue gains. The precise location of such a point varies enormously between taxes, countries and economic circumstances, and cannot sensibly be established by political ideology alone.
This is one reason why the best economic arguments are not simply for high taxation or low taxation. They concern the design of taxation: how revenue can be raised while causing the least unnecessary interference with productive activity.
Friedman’s commission and the political economy of bureaucracy
We can now return to Friedman’s original quartet of characters. A and B decide that C must surrender part of his wealth for the benefit of D. They then establish an institution to administer the transaction, with its own officials, offices, budgets and procedures. Before long, the institution may acquire interests that are quite separate from those of the people it was originally intended to serve.
This is a problem familiar to scholars of public choice theory, which applies economic reasoning to political behaviour. Politicians, bureaucrats and regulators do not cease to possess personal interests merely because they enter public service. They may genuinely wish to improve society while simultaneously seeking higher salaries, larger budgets, greater authority or professional advancement. The incentives arising from these objectives can influence institutional behaviour just as commercial incentives influence private companies.
A bureaucracy established to solve a social problem may be reluctant to acknowledge that the problem has been substantially solved. An organisation responsible for distributing financial assistance may develop an institutional preference for increasingly elaborate assistance programmes. Every additional regulation can create a corresponding demand for administrators, legal advisers, inspectors and compliance specialists. The continued existence of the machinery becomes an objective in itself.
Yet a distinction must be drawn between this administrative phenomenon and deadweight loss in the strict economic sense. The commission Friedman describes is not necessarily itself deadweight loss. An administrator’s salary is a payment for labour and may correspond to genuinely valuable work. Administration consumes resources, but some administration is indispensable to delivering public services fairly, efficiently and without fraud.
Deadweight loss refers more specifically to the net economic surplus destroyed through distorted decisions and foregone beneficial activity. The two costs can accompany one another, but they are analytically different. If a government spends £100 administering a transfer, that is not automatically £100 of deadweight loss in the textbook sense. If the taxation needed to finance the programme also prevents transactions worth £50 in net surplus from occurring, that additional £50 is a deadweight loss.
This distinction matters because otherwise Friedman’s observation degenerates into an indiscriminate complaint about public expenditure. The serious economic question is not whether officials are paid, but whether the activities they perform generate benefits commensurate with their costs and whether the system creates avoidable distortions elsewhere in the economy.
The same questions must also be asked of private institutions. Monopolistic corporations, professional cartels and businesses protected from competition can extract economic rents and create deadweight losses of their own. There is nothing uniquely governmental about the capacity of institutions to manipulate markets for the benefit of those controlling them.
The limitations of Friedman’s argument
Friedman’s aphorism nevertheless raises a philosophical difficulty that economists cannot resolve simply by producing equations. Why should economic equality be regarded as an objective in the first place? Equality is not the same thing as prosperity, and a society in which everyone is equally poor would hardly represent a triumph of public policy.
However neither does economic efficiency exhaust the legitimate objectives of government. A society may reasonably decide that protecting people from destitution, ensuring access to education or providing medical treatment to those who cannot afford it possesses a value beyond the immediate calculation of economic surplus. A hospital treating an impoverished child cannot sensibly be judged solely by whether the child’s parents would have purchased the treatment in an unregulated market.
Indeed the economic case for certain forms of redistribution can be compelling. Childhood education may increase future productivity, reduce criminality and improve public health. Preventative medical care may avert considerably greater expenditure later. Social insurance may protect individuals against risks that private markets cannot adequately cover, while assistance to those in extreme poverty may improve their ability to participate in economic life.
These considerations explain why economists have devoted so much attention to the problem of optimal taxation. The British Nobel laureate James Mirrlees made particularly important contributions to understanding how governments can pursue redistributive objectives while minimising the economic damage caused by taxation. The resulting literature recognises that redistribution may improve social welfare even when its financing creates deadweight loss.
The essential question is whether the benefits of redistribution justify its costs. A programme that produces £100 of genuine social benefit at an economic cost of £20 may be worth pursuing. A programme that produces £20 of benefit at a cost of £100 is considerably more difficult to defend, irrespective of how noble its stated objectives may be.
Even this arithmetic is incomplete because the distribution of costs and benefits matters. Twenty pounds lost by somebody living in poverty may have far greater human significance than twenty pounds lost by a millionaire. Economics can help clarify these trade-offs, but it cannot independently decide how much importance society should attach to equality, freedom, security or human dignity.
Interestingly Friedman himself was not categorically opposed to every form of state-financed redistribution. He advocated a negative income tax, under which people with sufficiently low incomes would receive financial assistance through a relatively simple tax-and-transfer mechanism. His preference was for assistance that reduced bureaucratic complexity and preserved individual choice rather than extensive governmental supervision of how beneficiaries should live.
There is therefore an important difference between Friedman’s actual economic thinking and the more extreme political interpretations sometimes attached to his aphorisms. He was not arguing that society must abandon those unable to provide for themselves. He was questioning whether elaborate coercive institutions were the most effective way of helping them.
Equality, efficiency and the experience of Ukraine
These questions acquire particular significance in a country such as Ukraine, where the consequences of economic inefficiency are not merely theoretical. Wartime government must allocate scarce resources between national defence, infrastructure, healthcare, humanitarian assistance and the preservation of ordinary economic life. Every unnecessary administrative burden risks diverting resources from activities that may be essential to national survival.
Consider the organisation of assistance to displaced persons. A governmental or charitable programme may require applications, identity verification, eligibility assessments, financial reporting and audits. Each procedure may serve a perfectly legitimate purpose, but taken together they can consume resources that might otherwise be available for accommodation, food, transport or medical assistance.
A badly designed programme can also discourage employment. If assistance is withdrawn abruptly when a displaced person finds work, the recipient may face a financial penalty for becoming more economically independent. A more carefully designed system might taper assistance gradually as earnings increase, preserving an incentive to work while continuing to protect vulnerable families.
Nevertheless wartime Ukraine also provides a powerful counterargument to any simplistic proposition that government intervention is inherently wasteful. National defence is a classic example of a public good that private markets cannot reliably supply in the necessary quantities. Air defence protects entire communities, not merely those individuals who volunteer to purchase it. Military logistics, reconstruction of destroyed energy infrastructure and the treatment of wounded soldiers cannot sensibly be left entirely to voluntary market transactions.
War also reminds us that freedom is not merely the absence of taxation. The capacity to exercise personal freedom depends upon physical security, functioning institutions and the rule of law. A prosperous private economy cannot survive indefinitely when the state is incapable of protecting it from invasion.
The appropriate lesson from Friedman is therefore not that government should do nothing. It is that government should be acutely conscious of the economic and institutional costs of everything it does. A country fighting for its existence cannot afford either uncontrolled bureaucracy or the ideological dismantling of institutions indispensable to its survival.
The same argument applies to international humanitarian organisations operating in Ukraine. Donors are entitled to ask not merely how much money has been spent, but how much assistance has reached those in need and whether the delivery mechanism has avoided unnecessary costs. Yet the cheapest programme is not necessarily the best one. Proper safeguarding, verification and financial controls may cost money while preventing far greater losses through fraud, incompetence or diversion.
Economics helps us distinguish productive expenditure from waste, but it cannot replace judgement about what society needs to accomplish.
The danger of pursuing equality for its own sake
There remains a deeper philosophical issue beneath Friedman’s observation. Economic equality can mean several quite different things. It may mean equality before the law, equality of opportunity, equality of access to essential services or equality of material outcomes. These objectives are not interchangeable, and policies designed to advance one may undermine another.
Equality before the law is compatible with substantial differences in wealth. Equality of opportunity may require public expenditure upon education and the removal of inherited disadvantages. Equality of economic outcomes, by contrast, requires continuing intervention to offset the differences in income and wealth that arise from people’s choices, abilities, circumstances and good or bad fortune.
The more comprehensively government seeks to equalise economic outcomes, the greater the potential tension with individual choice. People differ in their willingness to work, save, undertake risks and postpone consumption. If every resulting difference in financial circumstances is to be corrected by public authority, the state must increasingly supervise the consequences of private decisions.
This is where Friedman’s argument becomes most persuasive. An objective that sounds morally attractive in the abstract may require institutions of remarkable coercive power when translated into practice. Those institutions will be operated by fallible human beings, subject to political incentives, institutional self-interest and imperfect information.
Yet we should resist the opposite error of imagining that every existing inequality reflects a freely chosen or economically efficient outcome. Inherited privilege, corruption, monopolistic power, discrimination and unequal access to education can all produce inequalities that have little to do with productive merit. Correcting such distortions may improve efficiency rather than undermine it.
A society should therefore be suspicious both of compulsory equality and of the assumption that existing inequalities are necessarily justified. The most defensible objective is not equality at any price, but a system of institutions that combines economic opportunity, protection against genuine hardship and the greatest practicable scope for personal freedom.
Who pays the commission?
We may now appreciate the full significance of Friedman’s four imaginary characters. A and B make decisions, C supplies resources and D receives assistance. The political system encourages A and B to emphasise their good intentions, while the administrative system measures success through budgets, programmes and expenditures.
The economist asks a different question. What happened to the resources, incentives and opportunities that existed before the programme was introduced? Did the intervention generate benefits sufficient to justify its costs, including the economic activity that did not take place because people’s behaviour changed?
The answers may sometimes vindicate government intervention and sometimes condemn it. An intelligently designed redistribution programme may increase human welfare despite creating some deadweight loss. A badly designed one may enrich intermediaries, discourage economic activity and leave its supposed beneficiaries scarcely better off than before.
Friedman’s genius was to insist that the people exercising political authority should not be permitted to evaluate their achievements solely by reference to their intentions. They must also account for the resources consumed in pursuing those intentions and for the opportunities destroyed along the way.
Indeed there is a fifth character missing from Friedman’s aphorism. We might call him E. He is the entrepreneur who never started his business, the worker who was never employed, the customer whose purchase never took place or the inventor whose invention was never developed. His absence from political debate is hardly surprising because he has no organisation representing him, no government department administering his affairs and no newspaper headline announcing the loss of an economic activity that never occurred.
Yet he is often the person most profoundly affected by deadweight loss. He represents the prosperity that society might have enjoyed but never created.
The pursuit of equality is not inherently foolish, nor is the redistribution of wealth necessarily economically destructive. The provision of collective security, social insurance and opportunities for the disadvantaged can make a society both more just and more prosperous. But these achievements require disciplined institutional design, careful attention to incentives and an understanding that the economic costs of public policy extend far beyond the sums recorded in government accounts.
Perhaps the greatest lesson of Friedman’s observation is that good intentions are not an economic resource. They cannot finance hospitals, feed hungry people, sustain armies or compensate for productive activity that has been discouraged out of existence.
The economic prosperity upon which every ambitious social programme ultimately depends must first be created by human endeavour. And whenever A and B decide what C should do for D, they should remember that there may be an E whose contribution to society will never materialise because of their decision.
That is the real tragedy of deadweight loss. It is not merely that somebody has paid too much. It is that something worthwhile, which might have existed, never came into being.
