Those countries that see education primarily as an investment, take note!

"The 'education is good' mantra does not work everywhere (see chart). In some countries many students have to be content with the intellectual rewards of study."

Of course, this graph does not take into account what students studied in college. The proverbial major in Latin literature may not expect the salary of the go-getter engineering major. The U.S. graduates seem to be making a lot, even with a high percentage in jobs that don't require university training. But the underlying message might be that a country may not be able to provide intellectually challenging and financially remunerative jobs for all the kids it educates through college, and it not may see a lot of them leave to seek opportunities abroad.
