America Has Too Many Teachers
President Obama said last month that America can educate its way to prosperity if Congress sends money to states to prevent public school layoffs and “rehire even more teachers.” Mitt Romney was having none of it, invoking “the message of Wisconsin” and arguing that the solution to our economic woes is to cut the size of government and shift resources to the private sector. Mr. Romney later stated that he wasn’t calling for a reduction in the teacher force—but perhaps there would be some wisdom in doing just that.
Cato Institute scholar Andrew Coulson on how public school employment has soared over the past 40 years even as student enrollment has flat-lined.
Since 1970, the public school workforce has roughly doubled—to 6.4 million from 3.3 million—and two-thirds of those new hires are teachers or teachers’ aides. Over the same period, enrollment rose by a tepid 8.5%. Employment has thus grown 11 times faster than enrollment. If we returned to the student-to-staff ratio of 1970, American taxpayers would save about $210 billion annually in personnel costs.
Or would they? Stanford economist Eric Hanushek has shown that better-educated students contribute substantially to economic growth. If U.S. students could catch up to the mathematics performance of their Canadian counterparts, he has found, it would add roughly $70 trillion to the U.S. economy over the next 80 years. So if the additional three million public-school employees we’ve hired have helped students learn, the nation may be better off economically.
