In the Wall St. Journal this week, Robert Coulson of the Cato Institute writes,
America's public schools have warehoused three million people in jobs that do little to improve student achievement—people who would be working productively in the private sector if that extra $210 billion were not taxed out of the economy each year.
He then suggests that this economic efficiency -- along with America's low graduation rates, poor student achievement, etc. -- could be remedied by sending many more kids to private schools through vouchers and corporate scholarships.
