There might have been more respect for the teachers, but here is a little tale from my own grandparents.
During the war, in the area my maternal grandma lived, nobody actually went to school as children went to beg/steal/work. Children were mostly barefoot as they didn't have money for shoes.
You couldn't hang your washing out as it got stolen and people got mugged all the time. There were actually a lot of people carrying guns for their own safety.
There was a drunk father who beat his family so bad on a regular basis, that he mashed one of his children's brain to a pulp and his mum asked my grandma for refuge in her cellar as she had 7 other kids to feed and save from this man. I don't think there was much of an extended family helping out, it seems.
There were really other very horrible things happening which I won't go into.
The Germans once took all the mattresses from my grandma's house so the kids didn't have anywhere to sleep on - and the terror of my grandma knowing they could knock on her door any day and demand anything they wanted (which they did on a regular basis).
My grandma remembers giving birth to my mum in a dark cellar as bombs were devastating buildings all around and the hospital was actually bombed itself. There was no lighting available all night. When she woke up she saw my mum covered in ants from head to toe.
Rationing meant that one family (in my grandma's case 4 kids) were only entitled to one piece of black bread that was so stale and hard they had to soak in for a week to actually eat it.
They had to get the rest on the black market as my grandad, who actually was at war, was able to come back sneakily now and then and leave some money/bring food. Everything cost an arm and a leg and there were people speculating wildly and getting rich on people's basic needs, like food. There were beggars everywhere asking for food, as people were actually starving.
My father on the other hand, who was upper class, was home educated, some of his friends who did go to school went to highly exclusive private/boarding schools and they had servants/tea parties/food aplenty and other wonderful things like private piano concertos at his house by renowned musicians with flowing wine and champagne, whilst everyone else starved to death.
The good old war times aren't so rosy when you have your grandparents telling you the truth....
