i firmly believe that otaku culture was engineered by the US government to in order to pacify the japanese population
you see otaku culture is comsumerist where buying useless plastic and junk makes you happy. this distracts you from rebelling against the establishment and pacifies you into submission. i think american government had a great hand in developing otaku culture because they didn't want japanese to rebel and want the imperial japan back. this is also why anime started being aired worldwide in order to pacify the entire world into american capitalist subsurvance
