For those skimming the thread, this analysis takes opportunity cost into account. It would seem women mostly "do worse" because they stopped working during the marriage. As far as net cashflows from one partner to the other post-marriage, it'd surprise me if it wasn't mostly flowing from men to women. But, honestly, that's almost entirely obvious from the fact that men mostly continue to work and women often stop.
Well, we heard your hypothesis. Let's see your study.
Haha well I wouldn't put too much weight on your "study", an article by the atlantic... Modern news channels / papers show extreme bias in their reporting and editorial content these days.
