At my household both I and my wife have jobs, and our incomes are comparable. When at home the household duties aren't as evenly distributed. I'm ashamed to say I don't do as much around the house as my wife does. I've got to give her props. She handles the bill paying and the laundry along with washing the dishes (no dishwasher). I handle the mowing and trimming, the grocery shopping and makre sure that I keep the oil changed and the tires rotated (by taking the cars to the mechanics). Other household cleaning chores are split nearly evenly and I assist in the areas she normally handles. It seems to work for us. I love her for what she does for us and I'm not shy about showing that love with flowers, dates, and other assorted gifts. I can't say that's how all households work but I can assure you women work too hard. Here's more on the lack of balance between husband and wife.
Households in which the wife earns more than her husband are becoming increasingly popular, but what hasn't changed is the fact that the wife still does the majority of the housework. Even in homes with stay-at-home dads, wives and moms continue to do all the cooking, cleaning and laundry. A recent study found that women who earn more than their partners do just as much house work as women who earn less than their partners. (Buzzfeed)
