Bachelors spend a lot of money on women for sure: on taking them out, on buying them the occasional gift and especially on buying enough drinks for ourselves to work up the courage to talk to them in the first place. But no one spends more than a married guy. Redoing the living room, taking trips out of town to visit her family and (gasp!) even having a kid -- these are all big-ticket items I never touch. I may have commitment problems, but at least I’m earning interest on them.
