A 19th-century economist named Adolph Wagner made a prediction that came to be known as Wagner’s Law: As societies became wealthier, their taxes would rise. They would rise because people would want more of the services that government tended to provide better than the private market, like national security, education, medical care and a guaranteed retirement.

Wagner’s Law has proven truer than not, but there are still many people who would like to pretend otherwise. Specifically, they wish we could summon a country with a strong military, good schools, health care and comfortable retirements — but falling taxes. It’s a nice fantasy.

Yesterday, Larry Summers, the economist and former Treasury secretary, gave a lunchtime presentation in Washington laying out the statistics that debunk the falling-taxes fantasy. He effectively updated Wagner’s Law for the United States in 2017.
