I wish I had all the answers, although I think at least some of it comes from the onset of patriarchal dominance hierarchies around 6k years ago. We don't know how to be egalitarian and value people for whatever skills and aptitudes they have. Everything has to be stratified and positions in the pyramid of power must be constantly jousted for. It's madness when you really stand back and look at it, and so it's something that I write about quite a lot because once you see how it infuses everyone in most Western cultures, you just can't unsee it.
