" As soon as we stopped sleeping with our cousins and build walls, temples and a few decent nightclubs, society became too complex for any one person to grasp all at once, and thus bureaucracy was born. A bureaucracy breaks the complexity down into a series of interlocking systems. You don't need to know how the systems fit together, or even what function your bit of the system has, you just perform your bit and the whole machine creaks on. "
