Analysis of the class issue is an approach that would let us best understand the essential aspects of North Korea. The North Korean government's Class policy was well reflected in the living patterns of the people residing in regions above the 38th Parallel, and strongly affected the social structure there. The Proletariat class culture based upon the Communist community composed of the labor class and the poor class was rather quickly popularized, and such culture's presence was felt everywhere, the language, attire, behavioral patterns, and moral structure. Class examination is the best topic that could let us see through the appearances of the obvious, and allow us to understand the fundamental social structure formed upon such hierarchical class order. The objective of this study is to define the nature of the class order of the North Korean society. The Hierarchical class structure in North Korea is sort of an institutionalized, discriminational class order. The structure reveals how the laborers, employed peasants, poor peasants, middle peasants, wealthy peasants, clerks, intelligentsia, hand manufacturers, entrepreneurs, and landlords were all placed in the hierarchy structure, and what kind of roles they received from the state. What kind of opportunities all these entries were allowed by the Labor party, and how many options they had in terms of entering high education facilities, will show us how the class order of North Korea was rendered into a hierarchy structure. And it should also be studied how such hierarchical class structure remains relatively stable even today.
