To ramble further (might as well take advantage of being a bit squiffy!) I think today there is still very much an "us and them" attitude towards children. I often see posts from parents on MN describing their own children in really really negative terms, terms that I would never use to describe anyone, let alone my own child. I've seen it in schools, as a teacher too. There is very little attempt made to understand why a child is acting out - the automatic assumption is that they're "naughty" and "uncooperative" and that they're behaviour must be stopped by any (reasonable) means. IME children don't act out for nothing, they don't enjoy being in trouble and being disliked, they act out because they're troubled, or depressed or experiencing abuse.
When I was a teacher colleagues often commented on how well behaved children in my class were, even the ones who in previous classes had been a "nightmare," despite the fact that I rarely used sanctions and I never ever got cross or raised my voice. The extremely simple reason that was the case was because I didn't just assume a child was being naughty, I assumed they were having difficulty of some kind and tried to help them. Sometimes all that involved was letting a child zone out for a minute until they calmed down, other times it was a matter of convincing a child over a long period that I would never ever scream at them like all the other adults in their life had. I often think we expect a ridiculous amount from children. We expect them to sit all day in a boring classroom and not talk to their friends (how many of us ever do that at work??), we expect them to complete work on time, we expect them to put up with being shouted at and punished when we would never stand for that ourselves in our own work environment. I honestly think that if we actually treated children like real people instead of little annoyances the world would end up a much better place. I do think a small number of people are born bad, but the vast majority of cruel evil adults started out life as fresh babies full of potential and got so beaten down by the world around them that they didn't really have a hope.
