You're assumptions are incredibly wrong.
> Whether your wife has a job or not, the odds are good that she is doing more of the house work and child rearing than you are. That doesn't necessarily mean you need a bigger house, but it does mean that if she is not happy with the house, it is not a good idea to be all "meh -- not like she will divorce me over this."
She works harder than I do full-time; I am at home many nights without her, with the kids, while she wins more bread. We split responsibilities quite well but she'll be the first to tell you I am an All-Star dad. I usually clean the house as I'm the neat-freak of the family, and what most people consider clean is just getting started for me. I spent the first 9 months of our first child's life at home being a semi-stay-at-home dad, rearing her almost completely as my amazing wife positioned herself into a career that helped us tremendously and really aids in our lifestyle now.
We appreciate each other, but don't value one's output over another, except maybe at our places of work. We're a team and we play like one.
> A good kitchen and laundry area can make the women's work vastly less burdensome.
Agreed, although we upgraded these features and requests to pinpoint issue we both had, as we both split duties performed in these areas at least 50% (different areas and different weeks demand different percentages).
