Mr. Wanniski was an adviser to President Ronald Reagan from 1978 to 1981, and designed the Reagan tax cuts that propelled the U.S. economy out of stagflation and led to the great stock market boom that followed. As an advisor, he counseled Democrats as well as Republicans, pro bono, and developed pro-growth strategies for several governments. He believed in the collective wisdom of the electorate. “The electorate, being wiser than any individual in the society, is society’s most precious resource. It is the job of the politician to try to divine what it is the electorate wants.”
