His Project Syndicate column argues that education is not what we should look to for economic growth.
... [T]hough the typical country with ten years of schooling had a per capita income of $30,000 in 2010, per capita income in Albania, Armenia, and Sri Lanka, which have achieved that level of schooling, was less than $5,000. Whatever is preventing these countries from becoming richer, it is not lack of education.
A country’s income is the sum of the output produced by each worker. To increase income, we need to increase worker productivity. Evidently, “something in the water,” other than education, makes people much more productive in some places than in others. A successful growth strategy needs to figure out what this is.
Make no mistake: education presumably does raise productivity. But to say that education is your growth strategy means that you are giving up on everyone who has already gone through the school system – most people over 18, and almost all over 25. It is a strategy that ignores the potential that is in 100% of today’s labor force, 98% of next year’s, and a huge number of people who will be around for the next half-century. An education-only strategy is bound to make all of them regret having been born too soon.
