it’s important to recognize that the economic damage from obstruction and extortion didn’t start when the G.O.P. shut down the government. On the contrary, it has been an ongoing process, dating back to the Republican takeover of the House in 2010. And the damage is large: Unemployment in America would be far lower than it is if the House majority hadn’t done so much to undermine recovery.
A useful starting point for assessing the damage done is a widely cited report by the consulting firm Macroeconomic Advisers, which estimated that “crisis driven” fiscal policy — which has been the norm since 2010 — has subtracted about 1 percent off the U.S. growth rate for the past three years. This implies cumulative economic losses — the value of goods and services that America could and should have produced, but didn’t — of around $700 billion. The firm also estimated that unemployment is 1.4 percentage points higher than it would have been in the absence of political confrontation, enough to imply that the unemployment rate right now would be below 6 percent instead of above 7.
