In the movie, a family of four entered the rich President park geun-hye's house as servants by means, and all the food and drink depended on the rich family. They "absorbed" the wealth of the rich family and "parasitized" it in the rich family, but this is only a superficial phenomenon. In fact, as President Park's family, it is the real "parasite".
As capitalists, President Park's family can live a life of infinite scenery only by the self-appreciation of capital every day, while the poor work hard, but the surplus value is taken away by the capitalists, and they can't even live in a decent house. Capitalists represented by President Park's family are the real "parasites". Through the exploitation of the proletariat, they "parasitize" in the surplus value created by workers.
Secondly, there are many excellent metaphors in this film. Throughout the film, the man's aversion to the "smell" of gold drivers represents an insurmountable gap between the two, and it is also the naked discrimination of the upper class against the bottom people.
It is this "smell" that caused President Park to be killed by a gold driver. As the bottom people in bonus hunter, they are often ravaged by power, but they will fight back when they are in a hurry. This also embodies the truth that "the limitation of capital is capital itself". In addition to the taste, the stone that Min gave Yu Ji and the cockroach in Yu Ji's mother's mouth all have strong metaphors.
In addition, the film strongly emphasizes the differences between the rich and the poor. On the one hand, it is a meadow full of sunshine, on the other hand, it is a home washed away by heavy rain, on the other hand, it is the cock crow of President Park's house, and on the other hand, it is the dark basement of "Forever Day". There is only one door between the mansion and the basement, but it is a stone door that is difficult to push open.
The alienation and distortion of society can't be seen or touched, but it is there. The happy ending is an illusion, but there is some hope.
