Billboard: Happy wife = happy life

This is a photo of a billboard spotted in Kansas City, Mo, claiming that what your wife needs to be happy is... a remodeled kitchen, of course! I have to say, when I first saw this photo I thought it was a joke. Why, in 2012, do we still have this mentality that a "woman's place" = kitchen?

This is not even so offensive anymore as it is ridiculous. People who perpetuate this idea only make themselves look ignorant and illuminate the fact that they need to update their way of thinking. Perhaps we can start by not making ads like this? Or at least claim that it was tongue-in-cheek.
