If the terms of marriage were reversed and women were required to enter a legally subserviant position i.e. surrender their future income and their children at the drop of a hat, I very much doubt women would marry.
Marriage is an institution that appears to have "run its course" in terms of utility for men. I see many guys of marrying age in my office who avoid it like the plague because there are many pitfalls and very few advantages.
