Summers on shrinking government

The appropriate size of government will be a central issue in this year's election.  Harvard economist and former Treasury secretary Larry Summers wrote in a WP op-ed this week that a number of "uncontrollable" factors will lead to an even bigger government in future years.  There is no denying two of the arguments he makes: (1) we face a triple whammy from rising health costs per person, more elderly people, and higher longevity and (2) at some point interest rates are going to return to normal levels which will increase the cost of debt service.  Less convincing is his claim that the cost of government services will continue to rise relative to the price of goods produced in the private sector.  Careful process analysis of government activities and adoption of private sector benefits packages could turn this trend around. 

Currently the federal government is spending 25% of GDP.  Mitt Romney pledges to cut this to 20% (close to the average over the last 30 years) whereas his opponent has yet to pick a numerical target.  Summers thinks the "uncontrollables" will get federal spending up to 31% of GDP. 

WP columnist Robert Samuelson faults Summers for being silent concerning what should be done in the future:

What should the nation do? Summers punts. Here’s his column’s last sentence: “How government can best prepare for the pressures that loom, and how greater revenue can be mobilized without damaging the economy, are the great economic questions for the next generation.”

Wrong. They are questions for this generation. They loom now; the longer we ignore them — as we have for decades — the harder the choices.
