My family could have been described as solidly Upper Middle Class my father was a Criminal Lawyer who was public School educated along with his brother and two generations before him. My mother was also Public School educated and Oxford University, before deciding she wanted to serve society, because money was not a problem. My mother therefore became a teacher but would only teach in Grammar Schools. This was the furthest she was prepared to go, in terms of her public service.
Thus it was always certain my brother would follow his father to Prep and then Public School and of course he did. However, there was never any chance that neither I nor my Sister would be given any Private schooling. For us it was the local Primary and then my mum's Grammar School if we passed the 11+. That was not certain for me and i remember my mother telling me that I will go to the school that suits my ability and whether i was Grammar caliber. In the end i passed and from that moment on during my schooling my mother continually called me a 'lazy' underachiever non more so than my 2:2 from a very ordinary University. This in contrast to both siblings Firsts from Oxford and Cambridge respectively. My mum finally apologized to me many years later when I was finely diagnosed with the 'jackpot' of Autism, Dyslexia, Dyscalculia Dyspraxia and Irlens which tend to co -exist within ASD diagnosis .
However, back to the question of the thread, i know of several well of parents of friends at the time who were equally misogynistic about their daughters schooling.
