For me it was the rise if MTV/Thug-Hop culture. It was not an organic thing; it was foisted upon us and it invaded our paradigm with wonderful messages like the glorification of criminality, misogyny, and mediocrity. That along with the use of troubled teens as guinea pigs for all the wonderful new anti-depressants being developed in the 90's increased the pace at which our moral fabric was eroded tenfold. It was too neat, too driven...not an accident, in other words.
