Part A: Theories of Justice and the Right to Health Care
An Introduction to Bioethics.
It is 1962. A Seattle hospital has just built the world’s first machine that can keep people with failing kidneys alive — but it has only three treatment slots. About sixty patients in the area will die without it. Every one of them is medically eligible. The machine cannot be shared.
You are on the committee that must decide who gets the three slots.
Write or discuss:
The committee was real. At Seattle’s Swedish Hospital, seven anonymous citizens — a lawyer, a minister, a homemaker, a banker, a labor leader, a state official, and a surgeon — were handed exactly this choice.
Note
The committee’s mistake was not bad intentions. It was deciding life and death with no theory of justice — just an instinct about who “deserved” to live.
The reaction to the Seattle committee helped launch the field of bioethics, and within a decade Congress simply paid for dialysis for everyone who needed it (1972). But the deeper question never went away: when a life-saving resource is scarce, by what principle should it be shared?
Today we meet four serious answers — and test each one against a single donated organ.
By the end of Part A, you will be able to:
Distributive justice is the part of ethics that asks how a society should divide up benefits and burdens — here, scarce medical care — fairly.
Every theory will be tested on the same hard case, so the differences between them stay visible.
One organ, many candidates.
As of late 2025, more than 108,000 people in the US were waiting for an organ transplant. About 94,000 of them — roughly 87% — need a kidney (Organ Procurement and Transplantation Network (OPTN) 2025). Most will wait years; some will die waiting.
When one donated kidney becomes available and several patients match it, someone decides who gets it. That decision is distributive justice in its rawest form — and each theory answers it differently.
Each lens fixes on a different question — and that question, not a tidy formula, is what it brings to the bedside.
Notice these are not four answers to one question. They are four different questions — which is why, as we’ll see, they rarely hand down a single verdict on their own.
Utilitarianism says the just distribution is the one that produces the greatest total well-being. Count everyone equally, add up the benefits, and choose the option with the largest sum.
A first pass says: give the kidney to whoever gains the most good — usually the most years of healthy life. But “total well-being” is bigger than one patient.
The QALY. Health economists measure benefit in quality-adjusted life years (QALYs). One year in perfect health = 1 QALY; a year in poor health counts as less.
Britain’s NICE uses roughly this math to decide what the NHS funds — often around £20,000–£30,000 per QALY. It is the utilitarian instinct turned into a spreadsheet. But notice it answers “is this worth it overall?”, not “which patient deserves it?”
The strength of the utilitarian lens — maximize benefit — is also its danger.
John Rawls asked a different question: not “what maximizes good?” but “what rules would we choose if we were fair?” (Rawls 1971)
The original position. Imagine designing a society’s rules from behind a veil of ignorance: you know nothing about who you will be — your wealth, talents, health, or whether you’ll be the patient who needs the kidney.
Rawls argues that rational people choosing under that veil would not gamble on landing at the bottom. They would choose rules that protect everyone, especially the worst-off — because that worst-off person might be them.
Behind the veil, Rawls argues, we would choose two principles — and the order matters as much as the content.
Crucially, the first principle is lexically prior: you may not trade away basic liberties for greater welfare, however large the gain. That priority is exactly what divides Rawls from the utilitarian — no one’s liberty is a line item in someone else’s sum.
A caution Rawls himself would press. Rawls’s principles govern the basic structure of society — its constitution and institutions — not who gets the next kidney. Using the difference principle to micro-allocate one organ is an extension of his view, not a verdict it strictly delivers.
Read in a Rawlsian spirit (or its prioritarian cousin — give extra weight to the worse-off), the lens does two things:
Two patients match the one available kidney.
Robert Nozick rejects the whole question. There is no “just distribution” to engineer — only just transactions (Nozick 1974).
The libertarian focuses on one fact the other theories skip: the kidney belonged to someone.
Since 1988, Iran has run the world’s only legal, regulated kidney market. Living donors are paid — officially about $1,400, plus negotiated payments from recipients.
The result libertarians predict actually happened: Iran eliminated its kidney waiting list by around 1999 (Ghods and Savaj 2006). People who would have died on dialysis received transplants.
Important
The catch
In surveys, about 43% of Iranian donors said their motive was purely financial, and roughly three-quarters said selling kidneys should be banned. The sellers are overwhelmingly poor.
A market clears the list — by routing the burden onto people who feel they have no choice.
Amartya Sen and Martha Nussbaum offer a fourth lens: justice is about securing the real freedoms and functionings people need to live a fully human life (Sen 1999; Nussbaum 2011).
The capabilities lens asks not “who gains the most life-years?” but “what does this person need to function as a human being?”
The utilitarian counts a candidate with a permanent disability as gaining fewer “quality-adjusted” years — and so ranks them lower for the organ.
The capabilities theorist asks what this person needs to live a full human life, and rejects the idea that a disabled life is worth less. The disability lowers their score in one lens and is irrelevant to their claim in the other.
On the same disabled candidate, the two lenses weigh identical facts in opposite directions — and send the kidney to different people. Which considerations you treat as decisive has real stakes.
Each lens foregrounds a different consideration — and that, not a final verdict, is what it contributes.
| Lens | What it makes salient | Why it doesn’t settle policy alone |
|---|---|---|
| Utilitarian | total benefit, system-wide effects | depends on the empirical facts; can back many rules |
| Rawlsian | basic liberties, then the worst-off | governs institutions, not one organ |
| Libertarian | whose it was; consent; fair transfer | the proviso and “just acquisition” cut both ways |
| Capabilities | what a person needs to function | proponents disagree on what it requires |
Important
The single most common mistake in these debates is to say “utilitarianism requires a market” or “Rawls forbids it.” None of these theories delivers a policy by itself.
So the lenses don’t end the argument. They tell you what the argument is about — and that is exactly what the Seattle committee never worked out.
Look back at the Seattle “God Committee.”
In the US, the Organ Procurement and Transplantation Network, run through UNOS, matches donated organs to waiting patients by a published algorithm — not a committee’s gut feeling (Organ Procurement and Transplantation Network (OPTN) 2025).
The algorithm blends factors that, in fact, come straight from our four lenses:
“Sickest first” and “best outcome” often point at different patients — the sickest patient may do worst with the organ. No rule escapes the trade-off.
The US uses opt-in: you are a donor only if you register. About 48 donors per million people.
Spain uses presumed consent (soft opt-out): everyone is a donor unless they say no. Spain leads the world at 52.6 per million (2024) (Matesanz et al. 2017).
Why Spain really wins
The law is not the whole story. Spain pairs opt-out with the ONT — full-time donation coordinators in every hospital and skilled family support. Spanish families consent about 8 times in 10; the UK, also opt-out, gets about 6 in 10.
Infrastructure, not just the default rule, drives the result.
Even a need-based system has seams that wealth and preference can widen.
This is a live debate among serious philosophers — and it does not split neatly along left and right.
Allow regulated sales
Forbid them
Note both sides include egalitarians and libertarians — the disagreement is about consent, exploitation, and what money does to a thing, not simply about markets.
You are a healthy college student, deep in debt. A patient on dialysis offers you $30,000 for one of your kidneys. You can live a normal life with one. The exchange is voluntary, and it would save the patient’s life and clear your debt.
The US bans organ sales outright — the National Organ Transplant Act of 1984 makes it a federal crime (United States Congress 1984). Iran allows them, and has no kidney waiting list.
So the trade-off is stark and real: the US protects the poor from being pressured to sell, and tens of thousands wait — some die. Iran clears the list, and its sellers are overwhelmingly poor and largely regretful.
Discuss: If a regulated market would save thousands of lives a year, is banning it a moral stand — or a comfortable way of letting people die so we don’t have to watch the poor sell their organs?
Note
The same three ideas from research ethics return here — coercion, undue inducement, and exploitation — and they still come apart the same way: a kidney sale may involve no coercion at all and remain exploitative.
What the market case adds is a fourth idea the first three miss: commodification — the worry that some things (organs, votes, people) are degraded the moment they carry a price. That, not coercion, is what splits the debate.
The organ case was a stand-in. The same theories now face the largest distributive question of all: does a person have a right to health care at all?
Two kinds of rights.
“A right to health care” is a positive right. That is exactly why it is contested: it places a claim on other people’s resources.
Norman Daniels builds the strongest case for a right to care by extending Rawls (Daniels 2008).
On this view, health care isn’t charity. It’s what fair opportunity requires.
The libertarian (Nozick)
There is no positive right to care, because it forces some to fund others. Compassion may be a virtue, but it cannot be coerced through taxation without violating people’s just holdings.
The utilitarian
Whether to guarantee care is not a matter of right at all — it’s an empirical question. Guarantee it if and only if doing so maximizes overall welfare. The answer could change with the budget.
Daniels says opportunity grounds a right; Nozick says rights run the other way; the utilitarian says “right” is the wrong word. Three lenses, three verdicts.
The US is the rich-world outlier, and its pattern is revealing.
A new cancer therapy (CAR-T, a real treatment) can cost around $475,000 for a single course. A public insurer must decide whether to cover it.
How does each lens rule?
Which answer can you live with — and who pays for it?
We started with seven citizens in Seattle deciding who lived, and asked what principle could replace their guesswork. Four answered: the utilitarian (maximize good), Rawls (protect the worst-off), the libertarian (free transactions, even markets), and the capabilities view (secure what people need to function). We watched them split over a single kidney, over selling organs, and over whether health care is a right at all — with Daniels arguing it follows from fair opportunity.
We now have the values. Part B brings the facts: how the actual US health care system spends the most in the world and yet leaves Americans sicker and shorter-lived than their peers — and what, by these four lenses, we might owe each other.
Recall
State the difference principle and explain how a Rawlsian and a utilitarian would allocate one kidney differently.
Apply
A city has one ICU bed and two patients: a 40-year-old with a 70% survival chance and a 70-year-old with a 40% chance. Pick a theory of justice and defend who gets the bed.
Debate
Is there a moral right to health care? Defend your answer using Daniels and at least one objection to him.
