Something is changing with today's young fathers. By their own accounts, by their wives' testimony, and according to studies and other statistics, more men are doing more around the house. Jay Fagan, a sociology professor at Temple and founding editor of the academic journal Fathering, says the inverse relationship between hours worked outside and inside the home is a big reason: "When the mother is working full-time, it is impossible for her to do everything." But there's another aspect too, he notes: "The more you earn, the more it buys you out of some of the mundane responsibilities."
