In the 1960s, Friedman famously explained that "there's no such thing as a free lunch." If the government spends a dollar, that dollar has to come from producers and workers in the private economy. There is no magical "multiplier effect" by taking from productive Peter and giving to unproductive Paul. As obvious as that insight seems, it keeps being put to the test. Obamanomics may be the most expensive failed experiment in free-lunch economics in American history.
Equally illogical is the superstition that government can create prosperity by having Federal Reserve Chairman Ben Bernanke print more dollars. In the very short term, Friedman proved, excess money fools people with an illusion of prosperity. But the market quickly catches on, and there is no boost in output, just higher prices.
Friedman stood unfailingly and heroically with the little guy against the state. He used to marvel that the intellectual left, which claims to espouse "power to the people," so often cheers as states suppress individual rights.
He loved turning the intellectual tables on liberals by making the case that regulation often does more harm than good. His favorite example was the Food and Drug Administration, whose regulations routinely delay the introduction of lifesaving drugs. "When the FDA boasts a new drug will save 10,000 lives a year," he would ask, "how many lives were lost because it didn't let the drug on the market last year?"
He supported drug legalization (much to the dismay of supporters on the right) and was particularly proud to be an influential voice in ending the military draft in the 1970s. When his critics argued that he favored a military of mercenaries, he would retort: "If you insist on calling our volunteer soldiers 'mercenaries,' I will call those who you want drafted into service involuntarily 'slaves.'"
Well over 200 million were liberated from poverty thanks to the rediscovery of the free market. And now as the world teeters close to another recession, leaders need to urgently rediscover Friedman's ideas.
