Why we read Milton Friedman and Rose Director Friedman, "Free to Choose"

Brad DeLong.

"Lord, enlighten thou our enemies," prayed nineteenth-century British economist and moral philosopher John Stuart Mill in his "Essay on Coleridge" http://olldownload.libertyfund.org/Texts/MillJS0172/Works/Vol10/PDFs/Mill_1277.pdf. "Sharpen their wits, give acuteness to their perceptions, and consecutiveness and clearness to their reasoning powers: we are in danger from their folly, not from their wisdom; their weakness is what fills us with apprehension, not their strength."
For every left-of-center American economist in the second half of the twentieth century, Milton Friedman (1912-2006) was the incarnate answer to John Stuart Mill's prayer. His wits were smart, his perceptions acute, his arguments strong, his reasoning powers clear, coherent, and terrifyingly quick. You tangled with him at your peril. And you left not necessarily convinced, but well aware of the weak points in your own argument.
General William Westmoreland, testifying before President Nixon's Commission on an All-Volunteer [Military] Force, denounced the idea, saying that he did not want to command an army of mercenaries. Milton Friedman interrupted him:
General, would you rather command an army of slaves?
Westmoreland got angry:
I don't like to hear our patriotic draftees referred to as slaves.
And Friedman got rolling:
I don't like to hear our patriotic volunteers referred to as mercenaries. If they are mercenaries, then I, sir, am a mercenary professor, and you, sir, are a mercenary general.
And he did not stop:
We are served by mercenary physicians, we use a mercenary lawyer, and we get our meat from a mercenary butcherhttp://www.davidrhenderson.com/articles/0199_thankyou.html.
As George Shultz likes to say:
Everybody loves to argue with Milton, particularly when he isn't there.
Thinking as hard as he could until he got to the root of the issues was his most powerful skill. "Even at 94," Chicago economist andFreakonomics http://www.amazon.com/exec/obidos/ASIN/006073132x/ author Steve Levitt wrote on his website yesterday, "he would teach me something about economics whenever we talked" http://www.freakonomics.com/blog/2006/11/16/sad-news-milton-friedman-has-died/. In this morning's New York Times http://www.nytimes.com/2006/11/17/business/17milton.html, Chicago economist Austen Goolsbee quotes from Milton Friedman's Nobel autobiography:
Friedman said that when he arrived [at the University of Chicago] in the 1930s, he encountered a "vibrant intellectual atmosphere of a kind that I had never dreamed existed."
"I have never recovered."
His world-view began with a bedrock faith in people, in their ability to make judgments for themselves, and thus an imperative to maximize individual freedom. On top of that was layered a deep faith and conviction that free markets were almost always the best and most magical way of coordinating every conceivable task. On top of that was layered a powerful conviction that a look at the empirical facts--a marking-to-market of your beliefs to reality--would generate the right conclusions. And on top of that was layered a fear and suspicion of government as an easily-captured tool for the enrichment of cynical and selfish interests that sought to grab whatever they could. Suffusing all was a faith in the power of argument and the utility of reason. He was an optimist: people could be taught the truths of economics, and if they were properly taught then institutions could be built to protect all against the corruption and overreach of the government.
And he did fear the government. He hated government's and society's sticking their nose into people's private business. And he interpreted "people's private business" extremely widely. He hated the War on Drugs, which he saw as a cruel and destructive breeder of crime and violence. He scorned government licensing of professions--especially doctors, who heard over and over again about how their incomes were boosted by restrictions on the number of doctors that made Americans sicker. He feared deficit spending: cynical politicians could pretend that the costs of government were less than they were by pushing the raising of taxes to pay for spending off into the future. He sought to innoculate citizens against such political games of three-card-monte: "Remember," he would say, "to spend is to tax."
This did not mean that government had no role to play. Enforcement of property rights, adjudication of contract disputes--the standard powerful rule-of-law underpinnings of the market--plus a host of other government interventions when empirical circumstances made them appropriate: Mayor Ken Livingstone's congestion tax on cars in central London is Milton Friedman's. Friedman's negative income tax is one of the parents of what is now America's largest anti-poverty program: the Earned Income Tax Credit. And, most important, government had a very powerful and necessary role to play in keeping the monetary system working smoothly through proper control of the money stock. If there was always sufficient liquidity in the economy--enough but not too much--then you could trust the market system to do its job. If not, you got the Great Depression, or hyperinflation.
In his belief that the government was required to undertake relatively narrow but crucially important strategic interventions in order to stabilize the macroeconomy--keep production, employment, and prices on an even keel--Milton Friedman was in the same chapter if not on the same page as John Maynard Keynes, the economic giant of the previous generation whose doctrines and influence Friedman worked tirelessly to supplant and minimize. The Great Depression had convinced Keynes that central bankers alone could not rescue and stabilize the market economy. In Keynes's view, stronger and more drastic strategic interventions were needed to boost or curb demand directly.
Friedman and his coauthor Anna J. Schwartz argued in their Monetary History of the United States that this was a misreading of the lessons of the Great Depression, which in Friedman's view was caused by monetary mismanagement--or perhaps could have been rapidly alleviated by skillful monetary management--alone.
Over the course of forty years, Friedman's position carried the day. Federal Reserve Chair Ben Bernanke right now holds Milton Friedman's view, not John Maynard Keynes's, of what kind of strategic interventions in the economy are necessary to provide for maximum production, employment, and purchasing power, and stable prices.
Milton Friedman's thought is, I believe, best seen as the fusion of two strongly American currents: libertarianism and pragmatism. Friedman was a pragmatic libertarian. He believed that--as an empirical matter--giving individuals freedom and letting them coordinate their actions by buying and selling on markets would produce the best results. It was not that he thought this was natural law--that markets always worked best. It was, rather, that he believed that places where markets failed were atypical; that where markets did fail there were almost always enormous profit opportunities from entrepreneurial redesign of institutions; that the market system would create now opportunities for trade that would route around market failures; and that government failure was pervasive--that any expansion of government beyond the classical liberal state would be highly likely to cause more trouble than it could solve.
For right-of-center American libertarian economists, Milton Friedman was a powerful leader. For left-of-center American liberal economists, Milton Friedman was an enlightened adversary. We are all the stronger for his work. We will miss him.
