It’s not a mechanical phenomenon, but it’s overwhelmingly true that the people who make it to decision-making positions (that is, what they think of as decision-making positions) are those who conform to the basic framework of the people who fundamentally own and run the society. That’s why you have a certain choice of technocratic managers and not some other choice of people equally or better capable of carrying out policies but have different ideas.
Couple things come to mind:
1. This is probably why I’ll spend a lifetime doing technical jobs: engineering, development, architecture and such. It could be that I’m simply better at doing those things than I am at managing… or leading.
2. The quote from the Hitchhiker’s Guide by Douglas Adams: “Anyone who is capable of getting themselves made President should on no account be allowed to do the job.”
It’s not so bad after all.
