While I agree with everything you wrote, the "better ways" have a "cap" on how effective they can be. The root causes -- both in-group preference[1] and laziness/delegation to the "smart loudmouth contemporaries/smart-enough predecessors" -- will be things for the foreseeable future among humans. Some might even call them eternal / instinctive. Our whole civilization is based upon delegation/layering, but trust sure is tricky! Even the smartest humans fall prey to Gell-Mann amnesia[2] on topics beyond their expertise. Personally, I think most of what you wrote all connects to the cluster of wicked problems[3] that I think of as "Humanity Complete" (after NP-Complete transformability).

Very nicely put. Thanks for that.
I'd offer solutions, except for the trivial implementation detail that I don't have any. But then, if I did, I'd have a Nobel and possibly be the first president of the united planet.
