Roy Masters has social theories based on his knowledge of hypnotism, and the observations of Friedrich Nietzsche, Sigmund Freud, and Ayn Rand, in which there are three types of people: Submissive parasites, dominant predators, and enlightened human beings.
According to this classification, there is the enlightened man, free of desire and fear, content with his life, gracious, disciplined, virtuous, patient and tolorant, accepting of adversity. Roy Masters claims this to be the original state of mankind before the fall in the Garden of Eden (much of this philosophy resembles Buddhism, particularly Zen Buddhism, or the Shambhala warrior tradition as taught in Vajrayana Bhuddism. See: Chogyam Trungpa Rinpoche).
Outside of this, however, are people who are described as bestial and subhuman, striving out of trauma induced dependancy or sloaffishness, either towards obvious, tangible resources (money, shelter, or food) or for more subtle reasons (company, attention, distraction). There are two types of people in this group: Submissive personalities who parasitize off others, and dominant personalities who terrorize and prey on others.
Often, submissive personalities lure in their desires by willingly submitting to relatively dominant personalities in return for the safety, power, and prestige that the predator has gained for him or herself, in turn, the dominant personality needs the submissive to aid, comfort, or otherwise react to him or (occasionally) her achievements and presence. Both are thus often locked into a co-dependency which results in frustration, resentment, and ultimately mutual and/or self destruction due to the natural limitations of one to support the other's inherantly unrealistic standards and mutually selfish indignation, compelling one towards transgression and counter transgression, conflict compounding, sometimes to dangerous heights.
Roy Masters states that both types become frightened or jealous, and resentful when in the presence of a Human being, and will either try to destroy him openly through hostile aggression, or subtlely corrupt from within through sympathetic manipulation (Roy Masters often warns his followers of ever engaging in social activity outside of business or professional relationships, a rigid lifestyle which may be one reason why some suspect him of being a cult leader).
Roy Masters teaches that both predators and parasites will use a number of means of living off of others, often through subterfuge and opportunistic exploitation of other's needs, using false pretenses of aid, assistance, relief, or, most common of all "love".
Ever since the trauma of the fall, the latter type has been the prevailing order for humanity and foundation for all human society ever since, each generation being traumatized and then repeating their parent's coping methods, causing further trauma to their own descendants.
