It just amazes me when people look nostalgically at the good old days! I'm sure parenting was easier, because it was socially acceptable to be neglectful and downright cruel.
Chuck your kid in the back seat of the car (or even the boot if transporting numerous children.) Smoke in the car, in the house, in the restaurants and in the staffroom. Drink and drive. Child misbehaves and you sort her out by hitting her, and if you want to maximise humiliation remove clothing in order to do so. Sarcasm from teachers just fine, no problem. 'Stand in the corner - no, don't turn around, no one wants to see your ugly face' was a favourite refrain of my year 1 teacher in 1988. That one wasn't to me, although I remember it, but I got my bum smacked (hard!) by her and deposited in a corner for an entire afternoon. Didn't tell my parents because I'd have got the same treatment 
'Children had so much freedom' people sigh and look around them sadly. Plenty of freedom - but seriously, how could anyone think it was remotely safe or acceptable to have tiny children wandering off to fairs and parks in the evening alone?
We were made to watch videos at school featuring naughty children playing on railway lines, going off with strange men to see kittens, touching electricity pylons and playing by water - all came to various gruesome ends. The subtext was that it was YOUR responsibility to be safe, YOUR responsibility not to do something silly - not your parents to ensure that a seven year old was supervised by water or electricity!
Bullying was bloody rife. Gay children could not be gay for fear of torture unmatched. Racism was no problem whatsoever, and it showed itself in numerous ways. We had a special assembly when an Asian boy joined our school by well meaning teachers urging us to To Nice To Nazeef. We were nice to Nazeef, in the same way we would have been nice to a disabled child, or a stray dog, or a much younger child. He wasn't really one of us, he wasn't just a normal child with black hair and tanned skin. He was different. Makes me cringe to think of it!
If you had SEN, especially a condition like ADHD or ASD, forget any sympathy or understanding. If you had SEN leading to an obvious and undisputed condition, your treatment was akin to Nazeef's.
People talk about freedom in the good old days. Freedom to be white, NT, unhealthy and unsafe. No thanks. I'm glad I had my children in the 2000s.
