I have a hunch that his belief that history just “happens” and arcs effortlessly towards a happy outcome is a result of his upbringing as a pampered puppet. He was PLACED in a tony private prep school, PLACED at Occidental, PLACED at Columbia, PLACED at the law firm in Chicago where he met Michelle (and possibly placed into that marriage as well), PLACED into the Senate and essentially PLACED into the presidency by the media. He neither had to fight nor work any harder than reading a script for any of it. There is nothing in his life experience that would cause him to question that Marxist narrative.
There appears to be some doubt as to whether he ever actually attended Columbia.
