Brainwashed human (typically from the Western hemisphere) that believes that they cannot live without the trappings of western life. Eg: they will exhibit extremely neurotic behaviour if they are ever without their mobile-phone, television, gameboy, i-pod, fast-food, car, make-up etc.
Extra Terrestrial 1: These humans are funny creatures - they could live in perfect harmony with their planet but instead they choose to create systems and structures that become huge distractions from the truth.
ET 2: Yes, then they become addicted to that which they have created. I think that makes them system addicts just like the now extinct Grippolians.
