Different times, different attitudes.
Not the number of one parent families back then, single mums often had father figures for their children in the shape of granddads, uncles, brothers etc. More family support, living at home, not in some council flat.
And society in general had more respect for teachers, police, doctors, clergy etc.
Back then, you wouldn’t have had to have notices up in GP surgeries telling you that staff must not be abused or physically attacked.
It just wasn’t done, or to barge into school swearing at the headmaster and complaining about your child’s teacher.
Progress, I suppose.
