'Hiring a wife' is necessary. If men and women of high powered marriages are going to have a real home life with children, there is going to have to be a nanny at some point.
At various points my wife and I have been just about every combination from dual wage earner to dual entrepreneur to one each way to me unemployed with her working or her staying at home when I made enough or when I didn't make enough.
There has never been a time when we were both working that we didn't depend on some external resources, from live-in relative, to housekeeper, to babysitter, to day care center. This is a reality of the upper middle class, and I think it is a reality that goes beyond the contemporary back to my sorta-focus on Royalty. In other words there are age-old traditional solutions to these problems and Feminism has just trashed them for egotistical reasons that have distorted a lot of people's basic ideas about family and home life.
I say that the traditional work of nannies, nursemaids, midwives, domestics and cooks of all sorts has been diminished by feminists in American society. In order to give the contemporary woman everything she wants (which is nothing more or less than being a princess), feminism has made a foolish error which is to assert that every woman can be a princess. Oh irony of cruel ironies that they will ultimately discover that in order to accomplish the power and privilege of queens that the bonds of sisterhood will be feudal.
