From a 1990 essay comes the insight
"The ability to get ahead in an organization is simply another talent, like the ability to play chess, paint pictures, do coronary bypass operations or pick pockets. There are some people who are extraordinarily good at manipulating- organizations to serve their own ends. The Russians, who have suffered under such people for centuries, have a name for them-- apparatchiks. It was an observer of apparatchiks who coined the maxim, 'The scum rises to the top.' "
It is as insightful in its own way as "The Mythical Man-Month".
