I found the book a stimulating read. Having read Margaret Hunt's Women in Eighteenth Century Europe, I disagreed with your basic historical premise that women have hardly ever been powerful outside of the traditional female occupations and that almost all women gave up work when they married. I think Margaret Hunt's extensive evidence from Europe and beyond proves that this isn't true; that women, especially widows, have frequently exercised considerable and extensive power in trade and business outside of the home and that huge numbers of women have always continued to work after marriage and childbirth.
As a graduate and seventies feminist who juggled home and a demanding career from the time my children were tiny, I expected to empathise to some extent with the women in your book. In fact I couldn't. Their lives bore no relation whatsoever to mine or to that of my high-achieving daughter who now combines a full-time career with a young family. I hated the descriptions of these self-satisfied, beautifully-groomed women with their pearly white teeth and Jimmy Choo shoes, engaged in the pursuit of money and power at all costs.
I had little sympathy for the terms in which their success was defined. I certainly don't hold the view that higher education confers special powers or that Oxbridge graduates are automatically gifted, talented and useful in the workplace. Living in France, I can see that the products of the Grandes Ecoles would certainly benefit from a bit more reality. I think a spell on the minimum wage with Florence Aubenas' Night Cleaners might help them relate a bit better to the people they seek to govern and manage.
So my question is this:
In my view the world is essentially a messy place, full of uncertainties and compromise. Does it actually matter if these rarefied creatures you describe, ultimately become so fixated on their own success that they fail to reproduce and become extinct in a generation? Would the world not be a better place if they were replaced by women in positions of power who are not perfect, but who understand the compromises of managing limited budgets, work and childcare and who can relate to the lives of ordinary people?
