This is England 86 was an excellent example of what you say. I think for youths this is important as style and music defines a generation and gives them something to look back on in later life. GOing back through history you had the Teddy Boys, Mods, Skins, Punks, Casuals but since the mid ninities and the Brit pop/indie boom no clear style and music link. Like you say kids of today have no sense of identiy, no purpose, no place. Modelling themselves on no marks like Jordan and thinking they can all be famous by having zero talent.
What is sad is when older people, blokes in their mid twenties upwards have not grown out of this, still modelling themselves on actors or musicians, like Serge from Kasabian.
