By this argument, we should also be examining why we spend so much on education. In 2010, the United States spent 7.3 percent of its gross domestic product on education, compared with the 6.3 percent average of other OECD countries. Surely spending dramatically higher amounts than other countries, with no better effects, is enough to drive us to consider how we can reduce the costs of education - and should make us think long and hard before considering proposals that we should throw even more money at this. It's surely true that having a well-educated workforce improves productivity, but it's also true that having a healthy workforce does the same. I'm having trouble finding much difference between the two examples.
