Movie “Parasite” shows not only the gap between the rich and the poor, but also the vanity and envy that all humans share in a civil society. The son in the poor family isn’t satisfied with just finding a job (as a tutor for the daughter in the rich family), he wants his entire family infiltrated in the rich household. It then leads to the tragedy in the end. Human needs make people corrupt because what they need is no longer the basics of living, but pleasure, convenience or leisure that they desire. The inequality in the society is caused by corrupt human wants, for”those conveniences having through habit lost almost all their pleasure, and being at the same time degenerated into true needs, being deprived of them became much more cruel than possessing them was sweet; and they were unhappy about losing them without being happy about possessing them”(Discourse on Inequality, p.72). The wants will eventually becomes the needs, which will control humans. In “Parasite”, the characters, especially the poor family, are in some ways enslaved to their desires which ultimately leads to their own tragedy.
