October marks the International Day of the Girl Child. This year's emphasis is on education. In poor countries worldwide as well as countries in conflict, girls are deprived of education more often than their brothers. Thirty million elementary school-age girls are not in school. There’s no disputing that girls born in the U.S. have won the lottery of life compared to girls in poor and war-torn countries. But despite our prosperity and universal education, we still have work to do.
