My interpretation of the film is that it's a class-based critique of liberal immigration policy. This understanding is heavily informed by pic related.

Let's start by assigning classes to the various characters:
>Kim Family - Lower Class Outsiders
>Park Family - Upper Class
>Kevin's Friend - Upper Middle Class
>Housekeeper - Lower Middle Class
>Housekeeper's Husband - Lowest of the Low

Before the film starts, the Parks have two servants (housekeeper, driver) and are unknowingly subsidizing the existence of a third character in the basement. There is an additional academic (Kevin's Friend) who is somewhat independent. This represents a modern welfare state, where the middle classes work for the upper class, and the resulting profits allow for the distribution of benefits to the lowest class, either through taxation or civil society. This situation is stable with internalized hierarchies.

The Park family are wealthy, but naive and trusting, willing to listen to the words of Kevin's friend, as well as anyone else who they deem to be in his class.

The Kim family are failures. Through their laziness and stupidity (shown by their failure to fold the pizza boxes and the fact that Kevin has taken the entrance exam 4 times) they are unable to leave the lower class.

Kevin's Friend, needing someone to tutor the Park's daughter but fearing competition from his other upper-middle class classmates, recruits Kevin to take his place, believing that because he's a loser, he can be easily controlled. This proves foolish, and as soon as Kevin is inside the Parks' world, he and his family begin working to replace the existing staff and loot the pantry. Once the housekeeper was forced out, her husband was left to starve, and the Kims show no sympathy whatsoever for the man who is now their responsibility. Though the housekeeper and her husband are able to briefly regain control, things get violent. The Kims murder the housekeeper, her husband murders the Kim girl, Kim father murders Mr. Park.

The movie ends with the Park family moving away and the Kim family moving on, showing no remorse whatsoever for the destruction and havoc they've caused.

>To reiterate: A system exists with Upper, Middle, and Lower classes coexisting peacefully. Additionally, there is a group of Foreigners trapped in the lower class because of their own worthlessness. The Upper Middle Class imports one of these Lower-Class Foreigners into his world, thinking they can be easily controlled. The Upper Class naively accepts this. The Lower-Class Foreigner then drives out the Lower-Middle Class natives and replaces them with his own friends. However, as his family has no loyalty to the system, they begin to loot it. The Lower Middle Class strikes back, is defeated, and is the avenged by the Lowest Class of native. However at this point the damage is done. The Upper Class flees and the Foreigners move on in search of a new host, leaving the system in ruins.
