If all girls went to secondary school, then a United Nations study has found that infant mortality would be cut in half, saving three million young lives every year. About 12 million children would not have their growth stunted by malnutrition.
The future wages of girls would rise by 12 per cent for every extra year in the classroom, a tonic for the economies of poor countries that would create jobs and strike a blow against the Boko Harams and the other maladjusted chauvinist fanatics.
