I respectfully disagree. The real reason is much simpler: the overwhelming centrality of entertainment in our culture and in the daily lives of most people has reset the norms for thinking and experience itself. If they spend enough time every day in front of a tv screen people will come to prefer the soothing immersion in fantasy over reality of any kind. Intoxification and psycho-affective disablement by way of entertainment. Digital entertainment, supplemented by poor diet, lack of exercise, limited exposure to the natural world, disrupted sleep and drugs like cannabis produce a population that is zombified.
