I see what you're getting at, Blagsta. Is it not just the simple fact that kids behave in such ways because they can get away with it? I'm not sure that that this unifying idea of 'deep underlying problems' as it seems very much like some kind of post-modern excuse that ignores any kind of self-determinism on the part of the kids themselves. It completely absolves any sort of responsibility for their actions, which I actually find a little condescending. When I shouted at older people on buses or when they were on the other side of the road, I was fully aware of what I was doing and why I was doing it - for a laugh. And, when I got older and learnt it wasn't a laugh, I stopped doing it.
