In all seriousness, men want to date/marry subordinate women because of control. For the most part, women control the home, sorry it's sexist but true. Most of the household decisions are weighted toward the female, the mother if children are involved. A lot of times, the male doesn't want control of these situations and decisions, but will usually abdicate to the female.
The man in the workplace, on the other hand, is usually more agressive and control oriented. To abdicate control in BOTH places would be demasculating.
