“The Golden Age of Young-ja” is a popular novel that shows the 1970s. The novel was also made into a movie and became very popular, but it seems to be trapped in the mold of ‘hostess literature’ and ‘popular novel,’ which shows the stereotype of the lower class. But even if the 1970s’ ‘public’ includes intellectuals, middle class and workers, it is questionable whether the novel's main characters, the urban lower class, are included. This paper noted that “The Golden Age of Young-ja”’s main characters-“I” and “Young-ja” were the youngman who were isolated, lower class workers of the city. In the 1970s, these marginalized urban lower-class youths were used as tools for the nation's economic development ideology and abandoned by another social discourse. The main characters-from soldiers dispatched to Vietnam to scrubber, from maids to prostitutes- becomes a victim of national violence, which is only used through physical labor, in the ideology of the nation's economic development and is not protected. “I”’s experience in Vietnam overlaps with the situation of Young-ja who lost one arm, and the two comfort each other and unite. The artificial arm that “I” made for Young-ja makes ‘the golden age of Young-ja,’ but in other words, it conceals national violence. However, Young-ja’s one arm couldn’t be hidden even if she tried to hide it. The novel shows that the cover-up of violent reality can not be possible through the image of Young-ja’s one arm that resisting the misery of reality with the burnt one-armed body. And the one arm as the evidence of the national violence works as the ‘pa-sang-ryok(破像力)’.
