I'd say vast majority of start-ups are founded by people with some head issues in the direction of narcissism...Meanwhile, day to day actions are actually based on desire for self gratification (avoidance of feedback especially, things that generally make them feel well), with very short sighted planning.

I respect your bullet-biting with regard to equating startups and cults, even if I think your view is as ridiculous as it looks.

How is a theory that presupposes utterly self defeating behaviour at odds with, you know, defeat?

My point was that the cult death rates were similar to that of organizations which are not generally believed to be organized to gratify narcissistic leaders' egos but make money, which would have been a counter example that refuted your argument, except you then chose to bite that bullet and argue that businesses are exactly like cults in this respect and aren't counter-examples at all. So you're right that that argument no longer works, but you've done so only by making completely absurd claims which prove too much.

If you want to argue that businesses are cults and hence the equivalent death rates are consistent with both being about leader gratification, that's consistent. But it's absurd and I don't believe it for a second and I doubt anyone else will either.
