Look up the book “Snakes in Suits” by Robert Hare, an expert on psychopaths.
Psychopaths aren’t just criminals, they can also be rather successful, at least for awhile, in business. One example, Bernie Madoff.
Well, they have to look good. The system rewards any model of creation of a competitive atmosphere, one favoring psychos and workacoholics or work-hogolic. My doctor had a new nurse like that who started hiding records and puting things under lock and key, and he could not fire her because once fired, she would not tell him where she had hidden all this stuff. He eventually had to hire a consultant who watched her and completely redid the business and then was able to fire her.
So, in order to look good, they will be forced to work hard and show it off, and they hate it. But once they are there, the workplace becomes a nightmare of a political football, not even a place where people are supposed to work.
These people are compulsive like that, always on the attack. The weak or insecure is shrewed and always on the attack.
