As for your questions about engineers in political positions, did it ever occur to you that perhaps the training or psychology of engineers made them totally unsuitable for positions of leadership? That's certainly what a true empiricist would conclude when faced with your observation.

Einstein turned down the offer to be Israel's first president. If he had been an engineer, he probably would have jumped at the chance, and probably failed at the job.

Even Heinlein, who I know you admire, made the observation that scientists and engineers are psychologically and temperamentally unsuitable to even vote, certainly not to lead; that their talents are not based on public service, but on personal interests. He rejected the idea of scientists being leaders or being granted the franchise simply because they undersood the mechanics of physical reality. Physical reality has nothing to do with the social universe. Newton's laws are useless in politics.

And if you haven't figured that out by now my friend, I hope you never achieve any position of political power. You'll be the worse kind of tyrant, the kind who sincerely believes he's doing the right thing.
