„Unusually high rates of maladaptive behaviors are found among affluent youth beginning around seventh grade, including substance abuse, eating disorders, and even suicide attempts. These are thought to be a function of high rates of stress associated with a culture of competition and peer pressure, coupled with inattentive or permissive parenting in the context of depersonalized school settings.“
