anniemac, I think that in terms of widely available careers for women, as opposed to just "jobs", this is a relatively recent development in the 200 odd years since the Industrial Revolution.
It was seen as a sign of the lower classes for women to work after marriage and a lot of the work was jobs as opposed to careers. Yes there were some lady doctors, teachers etc - but even those women who had jobs beforehand, were expected to give up working when they married.
The issue is, that now women can have careers they still somehow end up caring the most about the family too, all those minutae details. I do feel that although it's liberating that women can choose to have a career if they want it, there is still more of an expectation on them to carry the can at home with regard to domestic commitments, more so than men.
In the past, women were constrained by it being harder to have a career as opposed to a job, and earn serious money, however they had more time to run a home and bring up children really well.
I do feel there is still a subtle pressure for women in particular, to run a home and bring up children really well, yet in having a career at the same time there simply isn't enough time in the day to do it all.
Sometimes I think that "Having it all" is actually more like "Doing it all" and in a way women have ended up boxed into an even tighter spot than before!
