Jeffrey D. Sachs: The New Progressive Movement

Jeffrey D. Sachs is the director of the Earth Institute at Columbia University and the author, most recently, of “The Price of Civilization: Reawakening American Virtue and Prosperity.”

OCCUPY WALL STREET and its allied movements around the country are more than a walk in the park. They are most likely the start of a new era in America. Historians have noted that American politics moves in long swings. We are at the end of the 30-year Reagan era, a period that has culminated in soaring income for the top 1 percent and crushing unemployment or income stagnation for much of the rest.

Decades on, America pays the price of that misdiagnosis, with a nation singularly unprepared to face the global economic, energy and environmental challenges of our time.

Washington still channels Reaganomics. The federal budget for nonsecurity discretionary outlays — categories like highways and rail, education, job training, research and development, the judiciary, NASA, environmental protection, energy, the I.R.S. and more — was cut from more than 5 percent of gross domestic product at the end of the 1970s to around half of that today. With the budget caps enacted in the August agreement, domestic discretionary spending would decline to less than 2 percent of G.D.P. by the end of the decade, according to the White House. Government would die by fiscal asphyxiation....
