For those of you who think feminism has served its purpose, a new study from the University of Washington shows that unmarried mothers are much more likely to land husbands if the little bastard is a boy, particularly when the husband in question is the kid's biological father. Since children from single-parent households are more likely to live in poverty, this is very bad news indeed for little girls. Previous research by the same authors showed that fathers of sons spend more money on their families.
