Well, they have a company together. One could assume that her husband (male/provider/aggressive) wanted to start a company and that she (female/nurturer/passive) joined to make it easier for him (as a real-world example, my girlfriends' mother does most of the administration for my girlfriends' father dentist business, but even if this work is highly appreciated it's clear which one of them is the dentist/owner/boss.) In short, this thinking is rooted in a rich tradition. Of stupidity, but still.
