Ours seems to be the age of the Partisan Hack. Looking over the list of best-selling books or the roster of columnists at top-drawer newspapers, success appears to correlate with mean-spirited attacks and heavy-handed rhetoric. Whatever happened to logical analysis of economic policy designed to illuminate as opposed to rabble-rouse? When I was young, economists Milton Friedman and Paul Samuelson wrote regularly for a major news magazine. They wrote to educate and to persuade.

In addition to an absence of reasonableness, today's economic journalism lacks perspective on technological dynamism. When I gaze into the future, I see rapid economic and technological change. While the economy as a whole will grow rapidly, the majority of today
