I have to confess I feel quite jealous of women in this regard.
While I probably wouldn't choose the lifestyle, I wish I had the option. I feel that we have reached a point where women are privileged to have the choice - perhaps for the first generation ever - to truly have the complete choice as to whether to pursue a career, or stay at home with the children, without too much judgement being placed upon them.
Men aren't in that place yet, and probably won't be for at least another generation or two. House husbands do exist, but are disparaged and sneered at by a society within which traditional gender roles and echoes of 'manliness' still pervade.
