From an interview with psychologist Robert Epstein, author of The Case Against Adolescence:
Teens in America are in touch with their peers on average 65 hours a week, compared to about four hours a week in preindustrial cultures. In this country, teens learn virtually everything they know from other teens, who are in turn highly influenced by certain aggressive industries. This makes no sense. Teens should be learning from the people they are about to become. When young people exit the education system and are dumped into the real world, which is not the world of Britney Spears, they have no idea what’s going on and have to spend considerable time figuring it out.
