Burger, C.
(1966).
Survival in the Executive Jungle.
"One executive who decided that, after all, every major company president already had his own corporate aircraft, topped them all by arranging round-trip helicopter transportation from his front lawn directly to the company parking lot each morning and evening. To the board of directors he provided many rationalizations: the helicopter conserved his precious time and energy; it wasn't that much more expensive than a chauffeured limousine. The true reason, of course, was that it gave him a feeling of importance that no amount of money could supply." (p. 170)
Buskirk, R. H.
(1974).
Modern Management and Machiavelli.
"The discharged employee is hopefully restrained from doing a great many things that he would like to do through fear of what it might cost him in terms of pay, good recommendations, and the law." (p. 168)
