From Wikipedia: ""communication occurs only between equals." Celine calls this law "a simple statement of the obvious" and refers to the fact that everyone who labors under an authority figure tends to lie to and flatter that authority figure in order to protect themselves either from violence or from deprivation of security (such as losing one's job). In essence, it is usually more in the interests of any worker to tell his boss what he wants to hear, not what is true."

Ultimately, the resources required to maintain a system prove insufficient.
