Most of us share an 'inheritance' of unhealed and unconscious feelings/emotions. These are 'the unconscious self' to a large degree. Much of these feelings are rage, terror, panic, fear and guilt. The net result of this being that many people who appear 'intelligent' are actually driven by aspects of themselves that they don't even know exist and thus their logic is broken, but it all occurs in their own blindspots. Since the societal investment in continuing to deny everything I have just said is so strong, they tend to congregate and even build entire nations on the unspoken agreement to deny how they really feel - hence 'manners' and many other forms of social control.

I feel this is a major aspect of the causation of all of this dysfunction, we can all heal ourselves and this is the most we can do.
