Traditional gender roles aren't even that traditional. It wasn't until after the second world war that some western families (still only some) could afford to raise a family on one income. In the 1920s, women, children, and men all worked. And we're getting back to that now.
So, it does seem like a fair question to ask. If everyone in the family (at least all adults) are fully employed, is it fair that only one of them does the cooking and cleaning? Probably not.
Having said that, most relationships are probably already a lot more equitable than you'd be lead to believe. Husbands and wives do roughly equal amounts of work.
Adam Sandler, surely.
Honorable mention for Gilbert Gottfried's annoying voice.
