Hierarchical, macho driven Society of current Korea owes its presence largely to the mandatory army system, which only little less than half of the population- young males are obliged to serve. The army operates as a mass production source for inequality and oppression for individual expression, and every year produces thousands of young man whose individuality has been liquidated. Furthermore, the annihilation of individual expression is justified and generalised, and even used as a bonding experience amongst men in social circumstances. Once back in the society, the discharged are two years behind in the career market from those of their female peers. It threatens big population of young men and enhances their insecurity on social status.
Korean society historically has its roots in highly homogenous, collective culture. Embedded tradition of confucious ideas in daily life also carries social presets for justifying discrimination in the name of cultural heritage.
