I think in general allowing children a lot more autonomy to develop their own judgement is good, and society has got overprotective. But I also think *some* changes are good: e.g. stepping in to prevent chronic bullying is a good thing, and having play areas on ground with some give instead of concrete is good -- people are going to fall *sometimes*. I get the impression these examples are not a total free for all (at least, in passing articles about them, I've not heard anyone complain about any of the likely problems if they were, only worry that there might be problems).
