My wife works outside the home and is currently bringing home most of the bacon in this house (it varies depending on my contract situation). I do the cooking, laundry, and the yard work. (Some yard work. Okay, hardly any yard work. It shows.)

Come to that, I've always done most of the cooking, although we do "take out" a lot, too.

I don't worry about who's doing "most of the work." Never have. You start going there, you start heading for trouble. Anyway, work is so varied, and done for so many different reasons and in service of so many different personal values, that there's really no common unit of work to go by, is there?
