It seems to me the very notion of the importance of emotional depth has been increasingly lost on most of us. What we consider deep is all too often ideological morality plays, with simplistic messages, intended both FOR simpletons, and with the aim of making our dialogue less nuanced, less precise, less probing, and less interesting.
Ponder Jon Stewart for a moment. He is the model for most millenials. He is, or was, seemingly all they seek: simple answers for complex problems, and a moral high ground bought through mockery.
