Some people crave to be winners, crave to be on top, to be above others. They will raise hell and bring down the heavens on your head if they don't get what they want. They want status, they want control and they are constantly spending every waking moment of their lives on figuring out how to achieve it, and don't care about much. These people will destroy your organization if they don't get what they want.
These are a separate breed from engineers. You can look up their CVs and I guarantee even if they started out in technical roles they didn't spend more than a year there.
As for are they viable from a societal standpoint, I'm not sure. They are essential for the functioning a certain type of highly toxic organization, just like lawyers and prosecutors are essential for a functioning legal system. Office politics is a negative sum game, but not playing is worse than playing it.
