Actually, my experience has been that the more educated women are the more choices they have, and often that choice can include staying at home or taking a lower-paid or lower-status job.
I'm still in touch with a couple of dozen female university friends. All but one now have children. All of us went on to have what you would call 'graduate jobs', some more ordinary than others, some really quite high-flying.
Out of all of us, only two went back to work during or straight after their maternity leave. One of those two then gave up work completely after her second child was born, and was much happier and relaxed because of that.
The rest of us all CHOSE to stay at home while our children were young. The fact we have had this choice is partly due to the fact that we are all educated, had good jobs and managed to get onto a decent financial footing before having children. In addition, we have all married men with a similar education and who have good jobs, thus making the financial aspects of losing one salary easier.
Virtually all of us have since gone back to work at some stage and in some way - some when their youngest child went to school, some when their youngest child started secondary school and the rest at various points in between. Some have returned to their original careers, although generally part-time (their choice), some have moved onto other jobs - yes, some of these jobs have been much worse-paid or lower-status than they previously had, but it has allowed them a much more relaxed life and better balance of work and home life.
So where is this artificial divide of 'women who work' and 'women who stay at home' that Xenia seems to see everywhere? Virtually all women I know do work or have worked and will probably work again at some stage. It's all about the many different stages of our lives and the choices we make to suit those stages. What works for one family at one particular stage will not necessarily work for them at another stage, so it's quite possible for a woman to work, not work, and then work again, and for that to be the right decision each time for her and her family.
