Okay, but the real point of my post is that - and remember, I agree with all the above said ChiTownScion - many women did do both and well in the Golden Era. I know two examples (one my grandmother) and, in her case, she was very accepted in her work place. And the same holds for the other example I know. In some communities, woman weren't kept out of work roles or denounced for working and raising a family, but I think these two examples are just that - examples of situations that don't fit the dominant model of the time.
For me, knowing these two women when I was growing up, seeing them as business women and seeing them accepted in their work and social worlds, made it harder for me to see the prejudices and stereotyping most women faced because my immediate and formative experiences didn't fit the dominant cultural view.
That's it - no big point to make other than my one-off experience was atypical and it took me a while to see the bigger cultural problem.
