I think the point is the reverse. Why are men happy to sacrifice family and everything else that really matters in life for the sake of the rat race, and women not as much? So, is that really a choice for all these men, or perhaps a necessity? What can be done to make it less of a necessity? (As I understand it, some Scandinavian countries have brought in the legal right to paternity leave similar to maternity leave, which strikes me as a good start.)
