Nothing is wrong with the kids, they are the same as they have always been.  They have the same impulses, desires and thoughts as kids for thousands of years.  What has changed is the way they are raised, the shape of the family, the influence of neighbourhoods, media exposure, etc.  Kids are no different than ever, their surroundings are, and it is the parents' job to deal with that.  Stop questioning the kids and start questioning their guardians, to do otherwise is a cop-out.
