There has never been a generation where women didn't work growstuff but in every generation, there have been some women who didn't. Post-war a lot of brain-washing went on to "encourage" women to stay at home and it worked to some extent. There were lots of nudge factors. You were encouraged to feel you were a bit further up the social ladder if you could afford for the "wife" to stay at home. I wonder if that is where the "Mrs Bucket" stereotype came from.
It's amazing that after fighting the views that encompassed "Kinder, Küche, Kirche" our own government tried to persuade us that the same order Hitler promoted with men in charge, protecting their family and women there to serve and nurture them was the right one. And it worked for quite a while but by the mid-70s, I would guess, as we needed more people working, feminism had been on the march again for some time and many women were better educated than they ever had been in such number it all changed again.
