Re: The Boeing angle
CEOs have to be replaced regularly because the system is based on those societies described in The Golden Bough which have kings that get sacrificed at regular intervals to ensure that the food supply continues. The idea of a board of directors that actually runs the business is just so 20th century.
The advantage of the system is that even the worst choice only lasts a few years, and if the human sacrifice element was reintroduced they wouldn't be able to go on to foul up another company.
One should never underestimate the extent to which the US (and the UK) at some levels is still firmly stuck in the hunter-gatherer mindset of 4000BCE or thereabouts. It explains how we can elect rulers who are simply better at throwing dung or pointy sticks than anyone else.
