The original question had to be edited down.  Of the wide ranging social policy that Pol Pot and his following wished to enact, the notion of egalitarianism and a perceived desire for equality seemed to be at its forefront.  The Khmer Rouge felt that Western capitalism had inspired a profound inequality in desires and in the way in which Cambodia was functioning.  Pol Pot's desire to ensure that people would embrace "a precious model for humanity" was rooted in his belief that total social equality was needed.  This meant, or was taken to mean, that anyone who possessed more education than another or who held competing points of view was deemed as an enemy.  It is for this reason that the social policy of Pol Pot embraced so much murder and state sponsored execution as part of its attempt to "reeducate" the citizenry.  At the same time, there was a clear establishment of wanting to "start over" from a social point of view.  The "Year Zero" element and Pol Pot himself being referred to as "Brother Number One" is reflective of this desire to start new, with people that had no history, no recollection of the past.

These elements constructed a profound shadow on the social condition of the people of Cambodia.  The "killing fields" resulted in mass graves, and vast numbers of citizens eliminated by the Khmer Rouge.  At the same time, the emphasis on rural peasants who featured little education helped to establish the basis for purges that wiped out many members of the previous government as well as urban Cambodians that had an educational background.  This helped to establish a social condition in Cambodia that enhanced fear, paranoia, and a sense of instability in how reality was perceived and constructed.
