“Money is an iron.”

This is the thesis statement of Bong Joon-ho’s Parasite, a beautiful film about the lengths that one family living in poverty will go to in order to climb the ladder of social success. As stated by a member of this quartet, money is an iron, as it irons out all the wrinkles in life, both metaphorical and literal, leaving behind flawless skin and a life virtually devoid of the anxieties of the common man.

A couple of years ago, a friend was taken on a date by a man of great wealth (she never mentioned his name, either to maintain the air of mystery or possibly due to an NDA). She described the evening, in which they were seated at a table in a clearing that was essentially devoid of people, servers appearing seemingly out of thin air when more wine was needed or to deliver unidentifiable gourmet foods and then disappearing back into the bushes. At the end of the night, when her host was driving her home in a wine-buzzed state, he tapped the rear bumper of another car. My friend watched as the wealthy man got out and talked to the other driver, the scene playing out in the Lynchian halo of headlights: no arguments, just a civil conversation, until finally her host took out his wallet, handed the younger man an amount of cash, and at the end of their discussion, the victim hugged the man whose car had struck his own. “In that moment,” my friend said, “I realized my whole life was a lie. Nothing matters. Money can do anything.” Money is an iron.

Kim Ki-woo (Choi Woo-shik, of Train to Busan) lives in a half-basement apartment with his parents and sister, all of them working odd jobs, like folding pizza boxes, to scrape by. One day Ki-woo’s friend Min-hyuk (Park Seo-joon) visits the family to deliver a suseok shaped like a mountain—and meant to act as a charm to bring the family wealth—and ask Ki-woo to take over his position as English tutor to the teenaged daughter of a wealthy family whose patriarch Park Dong-ik (Lee Sun-kyun) is the CEO of an IT company. Ki-woo, who is naturally bright but was unable to afford college following his required military service, is initially reluctant, but agrees to interview for the position with school documents forged by his sister Ki-jeong (Park So-dam), and is accepted for the role by the relatively simple-minded family matriarch, Yeon-gyo (Cho Yeo-jeong). Noticing that the couple’s younger, undisciplined child, son Da-song (Jung Hyun-joon), likes to paint, Ki-woo secures a job for Ki-jeong as the boy’s art teacher, under the guise of a friends cousin from art school in the U.S. With a little more finagling, he gets his mother Chung-sook (Jang Hye-jin) and father Ki-taek (Song Kang-ho, of Snowpiercer) positions working for the Park family as well. And that’s when things get . . . weird.

To say more would be to spoil the film’s various twists and turns, although all of them are foreshadowed beautifully: Ki-taek’s tendency to leave the windows of the family’s hovel open results in disaster, Ki-woo’s obsession with and allegiance to the rock that is meant as a talisman for the family’s upward mobility brings him nothing but misfortune, even Ki-jeong’s fortuitously lucky guess that something “traumatic” happened to Da-song when he was younger turns out to be true, after a fashion. For the Park family, money is an iron, as it not only frees them from difficulties others experience, but protects them from even having to be aware of them, as they live in an ornate, sun-kissed mansion surrounded by a perfectly manicured and maintained lawn—the only vegetation that we see in the entire film. Approaching the Park home from the street, there is only a set of stairs and a garage door visible, but once inside, the walls at the edge of the property make the house and its inhabitants seem completely isolated, the shrubbery creating an optical illusion as if there is no world beyond the edge, no starving people living in easily-flooded basements just subway stops away.

The Parks are not malicious people, just naive and separated from the rest of the world. The Kims are not evil either; they are merely trapped within a social structure that offers no legitimate or straightforwardly moral methods to escape from their social tier. The rules are different for the rich, and it shows in the way that they treat their domestic employees: Ki-taek may be treated like a trusted advisor and even a friend most of the time, but Dong-ik doesn’t hesitate to remind him that he is being paid when the former is hesitant to participate in a roleplay for Da-song’s birthday. The Parks also remark upon Ki-taek’s smell, noting that it is musty and “like the subway,” not that any member of their family has set foot in a subway in years, and Dong-ik’s involuntary reaction to being confronted by the scent unexpectedly plays a major role in the film’s resolution. Further, the Park family even fetishizes poverty at one point, as husband and wife lie together and he whispers to her about the eroticism of the “cheap” panties (actually Ki-jeong’s) that were found in the backseat of his car earlier in the film.

Money is an iron. For the Parks, it is the metaphorical iron that makes life smooth and effortless, and the iron strength of the walls that separate them from the riffraff below. For the Kims, it is the iron of prison bars that keep them in a metaphorical prison of society and, perhaps, a literal one; it is the weight that drags them down, a millstone to prevent them from ever escaping the trap of stratified social classes.
