Milton Friedman Took Free Markets Out of the Classroom and Into the Kitchen

Most professors of economics spend their careers writing for other professors of economics. Their papers are footnoted to the ceiling, read by a few hundred people, and understood by fewer. There is nothing wrong with that. Somebody has to do it.

Then there is the other kind of economist, the one who walks into the kitchen where a family is arguing about why the groceries cost more than last year, sits down at the table, and explains it without a single equation. Milton Friedman was that kind. He won the Nobel Prize in economics in 1976, which proves he could play the professors' game. Then he went on television, in plain language, and proved he could play the people's game too. That is the rarer talent, and conservatives ought to study it as much as they study his ideas.

This post tells you who he was, what he argued, and where the argument is strongest. I will also give you the best objection to his view, and his answer. A free-market case that cannot face the poor is not worth much.

Who he was, in brief

Friedman (1912 to 2006) taught for most of his career at the University of Chicago and later joined the Hoover Institution at Stanford. His technical work on money, with Anna Schwartz, produced A Monetary History of the United States, published in 1963. His popular work is what made him a household name.

• Capitalism and Freedom (1962) argued that economic freedom and political freedom support each other, and it applied that idea to money, taxes, schools, licensing and welfare.
• Free to Choose was a ten-part television series on public broadcasting, first aired in 1980, with a companion book written with his wife Rose Friedman. It put his case in front of a mass audience.
• He also wrote a long-running column for Newsweek and testified before Congress many times.

That is enough biography. The ideas are what count.

One: the vouchers idea

Start with a proposal that is older than you think. In 1955, in an essay on the role of government in education, Friedman suggested a simple reform. Keep the government's role in paying for schooling, but stop requiring the government to run every school. Give parents a voucher, a certificate worth a fixed sum for each child, that they could spend at any approved school, public or private.

His reasoning was straightforward. A parent whose child is assigned to a school by address has no way to leave if it fails. The school gets its money either way. Give the parent the power to take the money elsewhere and every school suddenly has a reason to care whether she is satisfied. Competition, in other words, does for schools what it does for grocery stores.

This is the intellectual root of the school choice movement. The first publicly funded modern voucher program started in Milwaukee in 1990, and the Supreme Court upheld a voucher program in Cleveland in Zelman v. Simmons-Harris in 2002. The foundation Friedman and his wife created in 1996, later renamed EdChoice, was built to advocate the idea. You can see the later chapters of the story in How a School Voucher Works, From the State Check to the Classroom Door and From Everson to Carson, the Court Cases That Opened the Door to Choice.

I will tell you where he got it right and where critics have a point. He got right that families who cannot afford to move to a better district are the ones trapped by the address system. Critics note, fairly, that voucher design matters: the amount, the accountability rules and the supply of schools all affect results. That is a debate about details, and it belongs in Seven School Choice Myths Your Neighbor Believes and What the Record Shows, not in a slogan.

Two: inflation is a monetary phenomenon

His most quoted sentence is that inflation is always and everywhere a monetary phenomenon. He put that line into circulation in the 1960s and 1970s, and it stands for a simple claim: if prices across the whole economy are rising year after year, the cause is that the quantity of money has grown faster than the quantity of goods. A single price can rise because of a drought. All prices cannot rise for long unless there is more money chasing the goods.

Why does that matter to your family? Because it changes who is responsible. If inflation is caused by greedy shopkeepers, then the answer is price controls and scolding. If it is caused by the money supply, the answer is to control the money supply, and that is the job of the central bank and, indirectly, of the Congress that sets the rules and spends the money. That is the chain of reasoning behind Inflation is the one tax that never needs a vote in Congress, and it is the theory behind the 1980s fight described in How Paul Volcker broke inflation and why it hurt so much.

Here is the idea with numbers, so you can see it. This is a made-up island, not a forecast. Suppose the island has 1,000 loaves of bread and $10,000 in circulation. If all the money is spent on bread, the price is $10,000 divided by 1,000 loaves, or $10 a loaf. Now suppose the island's treasury prints another $2,000 and the same 1,000 loaves are all there is. The money is $12,000, and the price becomes $12,000 divided by 1,000, or $12 a loaf. That is a 20 percent rise, from 12 divided by 10 equals 1.2. Nobody got greedy. Nobody hoarded. There was simply more money for the same bread. Real economies are far messier, because production grows and people hold cash for different lengths of time, but the logic of the island is the logic Friedman was pointing at.

I should be straight about the limits. Economists argue about how fast the effects arrive, which measure of money matters, and how much supply shocks play a role over short periods. Friedman himself said the lags between a change in money growth and a change in prices are long and variable. The claim is not that every price jump has a single cause. It is that sustained, economy-wide inflation needs monetary fuel.

Three: the draft

Here is a Friedman idea that surprises people who think of him as a one-note economist. He opposed military conscription. He saw the draft as a tax in kind, paid disproportionately by the young men unlucky enough to be called, and he argued that a volunteer force would be fairer and, in the long run, better.

In 1969 President Nixon set up a commission, chaired by former Defense Secretary Thomas Gates, to study an all-volunteer force. Friedman was a member. The commission recommended ending the draft, and the draft ended in 1973. Whatever one thinks of the broader debate, that is an example of an economist's argument about incentives and freedom shaping a major decision.

Four: the pencil parable

Now to the kitchen table. In the first episode of Free to Choose, Friedman held up an ordinary pencil and made a point that sticks. Nobody on Earth, he said, knows how to make a pencil. The wood comes from one place, the graphite from another, the rubber from a third, the brass band from a fourth, and thousands of people who have never met, and who may not even share a language, cooperate to put it in your hand without any one of them knowing the whole recipe. The idea came from an essay by Leonard Read, and it is the same insight Hayek had put in more technical terms. You can read about it in I, Pencil and the price system, how nobody plans your breakfast and in Hayek Explained Why the Smartest Planner in the Room Always Loses.

Why is this a good lesson? Because it takes an abstract claim, that prices coordinate strangers, and attaches it to a thing in your junk drawer. Friedman knew that argument is half persuasion. People will not remember a proof. They will remember a pencil.

Five: the objection that markets ignore the poor

Now to the strongest case against him. It goes like this.

"Free markets are fine for people who already have something to sell: skills, capital, a good school. But a market gives to each according to what the market values, and some people have very little to offer it. The elderly, the disabled, children in broken homes and workers whose industries disappear can all be left behind. A philosophy that says 'let the market decide' has nothing to say to them. Charity is not enough, and rights to private property are cold comfort to the person without any."

That is not a straw man. It is the objection that moves honest people. Friedman did not dodge it. His answer had several parts.

1. He accepted that poverty is a legitimate public concern. He thought that relieving poverty is a proper government function, in part because private charity suffers from a free-rider problem: everyone benefits when poverty falls, and each person is tempted to let others pay for it.
2. He proposed a better tool. In Capitalism and Freedom he put forward the negative income tax. Under it, a family whose income falls below a set level receives a cash supplement from the government, calculated on a sliding scale so that earning more income always leaves it better off. In place of a patchwork of in-kind programs, each with its own bureaucracy and rules, it would give the poor cash and the dignity of choosing how to spend it.
3. He argued that the existing system was worse. His complaint was that a thicket of overlapping programs creates high effective tax rates on poor families as benefits are phased out, wastes money on administrators, and treats recipients as wards rather than adults.
4. He pointed to growth. A rising economy lifts the bottom faster than any redistribution scheme. That is the point of The Best Antipoverty Program Ever Tried Was Letting People Trade.

Here is the negative income tax with hypothetical numbers. Say the break-even line is $20,000 and the government pays half of the gap between a family's earnings and that line. A family earning nothing receives half of $20,000, which is $10,000. A family earning $10,000 receives half of the $10,000 gap, which is $5,000, for a total of $15,000. A family earning $20,000 receives nothing, and has $20,000. Look at the pattern: every extra dollar earned still leaves the family with fifty cents more than before. That was the whole point. A system that takes away a dollar of benefits for every dollar earned punishes work. His design never did.

Did the idea take hold? Partly. The earned income tax credit, enacted in 1975, works along lines related to his thinking: it supplements the income of low-wage workers and rewards work. Its supporters across the spectrum have claimed it. It is not his proposal, and the arithmetic of how it phases out has its own problems, but it is the nearest cousin in actual law.

Where do the critics still have a point? A cash supplement does not fix a failed school, a broken family or an addiction. Friedman would have agreed that markets are not a complete answer to every human problem. He claimed only that they are better than the alternatives at the thing they do, and that government should do a few things well rather than everything badly. Reasonable people can weigh that differently, and I will not pretend the debate is closed.

The honest footnote

A good profile includes the awkward bits. Friedman worked at the Treasury early in the Second World War, when income tax withholding from paychecks was introduced. He later said he regretted his part in it, because withholding makes taxes less visible and government easier to grow. I find that admission more persuasive than any slogan. A man who will tell you that he helped build something he now thinks is a mistake has earned a hearing.

What to take from him

I would draw three lessons from a career like Friedman's, and only one of them is about economics.

• Explain it so the person at the table can repeat it. If your argument needs a graduate degree, it has not been finished.
• Pair the principle with the practical alternative. He did not only say the old system was bad. He offered the voucher, the negative income tax, the volunteer army. When you criticise, propose.
• Take the objection seriously. His reply to the argument about the poor was not "the market will provide." It was a specific proposal. That is why people who disagreed with him still read him.

If this is the kind of thinking that draws you in, Seven Myths About the Free Market That Deserve Retirement is a natural next stop, and Thomas Sowell Asks What Happens After the Policy Passes covers another economist who built a career on asking what happens next.

The bottom line

• Prices rising everywhere means too much money chasing too few goods. Judge any inflation story by asking where the money came from, and who controls it.
• Money for education belongs to the child, so let the family choose the school. The best argument for school choice is that a parent with no exit has no power.
• Freedom is an economic argument and a moral one. The draft, the school monopoly and the maze of benefit rules all cost people something they cannot get back, and Friedman's instinct was to give the choice back to the person.
• A free-market case owes the poor an answer. Friedman's was cash, work incentives and growth. You may think it is incomplete, but you should be able to state it.
• Learn the pencil story and tell it. It is the shortest argument for free exchange you will ever make, and a child can follow it.
