How do know it's increasing? From your article:
While the anecdotal information continues, few studies have emerged giving factual data on how serious this issue has become.
That is one of a legion of articles and information about the increasing prevalence of this...added to my own experiecne in a very upscale suburban area where every PTA and parents organization has the issue on red alert, right at the top the list because of it's epidemic trend.
Before you go on living in denial-- try researching the topic--you'll find lots to read about this.
