Only by assuming some great generalization about human nature can one make the argument that a majoritarian system is just. PSA does not make this mistake. PSA begins with the observation that humans are somewhat unique among known species in that there is great variance from the nature of one individual to another. Thus, we recognize the fact that some individuals are more intelligent than others. Some individuals are more ethical than others.
Some individuals are more industrious, or creative, or adaptable than others.
The variation within our species is great. Any system that makes the assumption that some portion of this nature should become the universal fountain for all law and organization does a grave disservice to those individuals who diverge from this narrow assessment. PSA observes that, under democracy, the best and the brightest are oppressed. Law, made for and by the majority, imposes upon individuals, sufficiently intelligent and ethical to govern themselves, constraints that are fit only for the lowest common denominator within the varied expression of human nature. Furthermore, democracy enshrines the values of the mediocre as the de facto standard by which all is measured and to which the teat of the state is given.
