The more I think about it and list it all the sadder I feel about the world my children live in.
Well, I don't. It's very personal, isn't it? I wasn't miserable as a child but my children had a better childhood in the 90s and 00s than I did in the 60s and 70s - on balance.
They had a better diet and better health care.
They had (at nursery and primary level, anyway) a better education. (At secondary it was probably very similar.)
Money was a lot less tight so there was no atmosphere of teetering on the brink, which is one of the things I recall being aware of. We could afford decent holidays (occasionally, anyway) and the four of us (two parents, two children) enjoyed each other's company. When they needed new clothes or shoes they got them. If we fancied a takeaway or going out for a meal or an outing, we did it. There was enough money for extracurricular activities like piano lessons and chess club.
If they misbehaved, by and large we managed to deal with it by talking. When I was growing up, hitting children was commonplace both at home and at school. It wasn't just not condemned, in many circles it was almost encouraged. Bullying was not challenged (and it often came from teachers, not just fellow pupils).
OK, they didn't have as much freedom to roam as I had, but that wasn't an unmixed blessing. We tend to forget the children who died or were injured in accidents, or suffered abuse or bullying in the time they were wandering about unsupervised by their parents.
