Well, it's cultural, undoubtedly. Many couples just do it that way because that's "how it's done" without really thinking about it. But as far as I've seen/heard there is also significant social cost to stay-at-home dads. They're alternately demonized, ignored, assumed incompetent, assumed less worthy for not financially supporting the family, or just not accommodated in a thousand other ways. That's what we (society) should challenge and change, IMHO. It would be a huge win for women and for men alike.
