I don't see why we're criticising kittywits.. millions of women around the world live in a similar situation, e.g. man earns and provides, woman takes care of kids and home. She seems like an extremely confident and sorted woman.
I think it's just that for those of us who want more equal partnerships in the sense that both partners have a career which fulfils them plus a home life, it's so recent that we have 'escaped' from the old model, and probably most of our parents fit the old model, that it makes you feel a bit panicky to hear about people that still live this way.
My dh is a modern man who believes in equality, and who does 50% of the housework etc, and will do 50% of babycare when it comes along in Oct, but IF I really insisted on staying home with the kids and doing the housework, in a regressive kind of way he would probably secretly get some satisfaction from that: after all, it is great to have someone cleaning up all your crap and making your home nice, so you don't have to. And also, in a regressive way, I can feel the residues of the old world pulling at me, saying 'you should make a comfortable home for DH' or at the very least making me feel just slightly guilty if we've run out of milk, as though it was more my responsibility than his to remember to buy it. So there is that little underlying struggle in your mind, and you DO have to keep your career goals in mind, keep remembering not to take on a housewifely role, and keep taking responsibility together with partner for creating your own little egalitarian utopia, otherwise, yes, it might be quite easy to slip into doing what your parents did and listening to those old messages of what women and men are good at. And then personally, I would end up extremely resentful and frustrated because it's not what I really want or who I am.
So I think the example of people who firmly live in the old model, which of course works for some, makes those of us who are trying with various degrees of success to live in newish models of partnership, feel queasy and scared because the old model is still a very strong prototype in our minds..
That's the whole thing I suppose about social change, there's people right at the front bravely struggling on and probably having quite a difficult time or dealing with stigma (SAHDs, very innovative family friendly working models), then a new mainstream (e.g. working mothers trying to get partners to do enough in the house), then a previous mainstream (housewife at home, man in the office) who are pulling backwards.
For me, DH's willingness to share everything with me, finances, housework and childcare, is part of the point of being married (or in a partnership). We're sharing the same life, not cocooned in different worlds as someone said earlier.
On a lighter note, there must be a reason why Athena sold SO many of those posters with the sexy guy holding a baby!
