Economic Insights FEDERAL RESERVE BANK OF DALLAS VOLUME 7, NUMBER 2 Milton Friedman Economist as Public Intellectual If asked to name a famous economist, most Americans would probably say Milton Friedman. Economists usually make their contributions behind the scenes at think tanks, gov- ernment agencies or universities. Friedman has done that, but he also has taken his ideas and policy proposals directly to his fellow citizens through books, magazine columns and, especially, television. It is not an exaggeration to say he has been the most influential American economist of the past century. He has changed policy not only here at home but also in many other nations, as much of the world has moved away from economic controls and toward economic freedom. Milton Friedman marks his 90th birthday on July 31, 2002, and the Dallas Fed commem- orates the occasion with this issue of Economic Insights.

After the war, Friedman spent a year teaching at the University of Historical Myths in American Economic Development Minnesota, then took a job at the University of Chicago in 1947 and While the nineteenth century was a period of rugged individualism, almost every other feature stayed there until his retirement from of the myth [of the robber barons] is false. Far from being a period in which the poor were being teaching in 1977.

The evidence of this is to be found in the statistics that economists have con- nesianism.

The fact that East Friedman, a classical liberal who Germany had to build a wall to keep people from going to West Germany is striking evidence of which believes in free markets, opposed this country had the better conditions of life. In the same way, the fact that year after year hundreds of thousands of people left the countries of Europe to come to this country was persuasive evidence that view and the theoretical mechanisms they were coming to improve their lot, not to worsen it.
