The essential problem is that most people can't accumulate, synthesize, and understand the requisite knowledge to appreciate that fact. We're strongly limited by our perspectives, which tend to become more rigid with time, just as we're having maximal influence on the lives of others. We're tribal, we're competitive, and we find it difficult to relate to distant strangers in vast numbers. As a result people eschew the attempt to gain a broad view of the world, and its history, and instead decide to trust an ideologue, ideology, religion, or just as likely these days, invent their own bullshit and find others with similar flavors of crap. "Oh you think the universe is crystals and orgone? Me too!" "Oh you think that black people smell funny? Me too!" "Oh you think the moon is an illusion created by God?..." You get. At the top you have people with enough money and time, power and education to appreciate these factors. Most of them seem to be in it largely for themselves, and even those who later come to some kind of humanitarian spirit do so in a fractional way compared to their total wealth. Exceptions exist, but they are so rare we all know the names. Is it any wonder that in a world of such massively "Haves" and brutally "Have-Nots", that each group invents a largely specious narrative to explain the actions of the other?
