I personally think that the "successful pyschopaths" meme is also way overblown, but I don't really know. I think being a psychopath is actually a deficiency, not a super power. Also in business I think people who help other people tend to be more successful overall than the stereotypical ruthlessly selfish people.
Edit: I think you added the link later on, that cites 21% of CEOs to be psychopaths? I would wait for replication on that one. It reminds me of another thing I read where reading about economics allegedly turned people into psychopaths (which is of course bullshit - just because you learned about rational decisions, as perhaps most CEOs do at some point, doesn't mean you are a psychopath). I suspect the questionnaire or the study they used to determine the "21%" number may in fact be motivated by politics.
Of course psychopaths exists. Most people are not psychopaths, though. And especially the CEOs you mention may have problems to persist.
I still prefer those "CEO psychopaths" to people feeding on government money (people in useless jobs paid for with taxpayer money).
