According to Freud, we all have egos, egos that are tossed between morality and sheer Darwinian need. So, it's pointless to say that I have an ego thereby.
Your thread begins with a question of perceptions; however, you err when you make a statement that says "due to the years spent training, and due to age, all perceptions are thereby correct," or as you put it, "But from each persons perspective, based on their years of training, they are all correct." What you desire to do is argue that "perspective" or one's encounter with qualia is a universal qualia. However, as modern cognitive science tells us, one's experience cannot be mapped via a neuronal pattern; therefore, experience as the Buddhist "Jin Gang Sutra" teaches, is quite empty.
