Governments and societies face similar choices. Do we spend on the army or agriculture (the old "guns or butter" dilemma)? In developing societies, where resources are especially short, the choices are even more difficult. But the essential question remains: what kind of investment will create the best future for everyone?
There is perhaps no better example of "enlightened" self-interest in the world today than the education of children. By every measure, every study, and every rational thought process, the investment made today in the education of girls and boys pays dividends that will last far into the future -- and make the world a much better place.
