In many poor countries, the greatest unexploited resource isn’t oil fields or veins of gold; it is the women and girls who aren’t educated and never become a major presence in the formal economy. With education and with help starting businesses, impoverished women can earn money and support their countries as well as their families. They represent perhaps the best hope for fighting global poverty.
