Most CEO have stock options so in theory they have skin in the game. This however does not make them rational or competent actors. Maybe skin in the game isn't all that it is being made out to be, it is probably necessary but not sufficient to be a effective business leader. Honestly this article feels strangely malicious, I would not call the execution of more then 300 soviet officers an example of skin in the game, but just cruel intimidation by Stalin.
