[Harmless Teddy Bear]

If the corporations run by psychopaths compete more successfully in the marketplace, then why would they want to exclude them?

Because they are an unacceptable risk.

They are not interested in the company but in their own impulses and desires. So having them in charge means that if selling out the company means they would get one of their own desires satisfied they will do so without hesitation.

So there goes your billion dollar company down in flames because your psychopath in charge wanted to have sex with a rattlesnake.

“So there goes your billion dollar company down in flames because your psychopath in charge wanted to have sex with a rattlesnake.”

That seems to conflict with your initial statement that they are an “acceptable risk”.
