You really are very single-minded Xenia. Or perhaps that should be dual-minded, because your only topics of conversation seem to be that private schools make for better people and that non-working women are somehow second-class citizens with drab lives.
Many women who choose to stay at home with their children have rewarding lives, and many do re-enter the workplace at a later date.
I am still 'at home' despite my youngest child being nearly 10, and I think I am really fortunate. I am lucky enough to meet a varied lot of sometimes fascinating people in the voluntary work I do, I use my brain, and indeed the area of expertise in which I have a degree, in some of the voluntary projects and research I am involved in, I am around for every single holiday, TD day and day off sick my children have, I am there when they finish school,I have never had to pay a penny in childcare, and yes, I occasionally do a bit of cooking and cleaning too.
My children know I am well educated, they know what jobs I have had, they remember the years when I was a 'full-time mum' in the daytime and worked in the evenings and weekends (now that IS hard! The best and worst of worlds in some ways), and they are aware of all the things I am involved in now.
They know that most of their friends' mothers work, so don't see women as 'just' housewives, and they also know that some of those families have very large household incomes as a result. However, again from their friends' point of view, they also see the downsides of having both parents working.
Housewives do not necessarily breed housewives. In fact in my own case, my mother did work when we were children, and it was one of the factors that reinforced my own choice to be at home with my children.
Education is always valid, no matter whether that child will go on to work full-time for 40 years in a high-flying career, will choose to stay at home looking after children, or as increasingly many do, to have several years not working and then return to work.
To try to turn a discussion about private schools into an anti-SAHM debate is very sad and misguided.
