Dec. 4 (Bloomberg) – For its 85th anniversary, Bloomberg Businessweek chronicles the most disruptive ideas of the past 85 years. In 1974, economist Arthur Laffer sketches his theory of tax policy over dinner with Wall Street Journal writer Jude Wanniski and Ford administration officials Donald Rumsfeld and Dick Cheney, kickstarting the rise of supplyside economics. Forty years after one of the most famous dinnernapkin doodles in American history, Laffer, Cheney, and Rumsfeld reunited at that same restaurant. (Video by Brandon Lisy.
