The Parks fail to realize their servants are related not because of a plot hole, but because their extreme class isolation blinds them to the humanity of those who serve them. In the Parks' hyper-capitalist reality, domestic workers are not viewed as multi-dimensional individuals with families and social networks; they are merely functional utilities designed to perform specific tasks. This is structured visually through the film's staging. The Parks consistently look down or away from their employees, maintaining strict boundaries of crossing the line. For example, Yeon-kyo readily accepts the recommendations of her current staff because she relies on a closed, elite referral system, assuming that a high-class endorsement guarantees quality. She is too polite, wealthy, and self-absorbed to investigate the personal lives of the help. The Kims exploit this systemic blind spot by adopting distinct professional personas and never interacting familiarly in front of their employers. The Parks' ignorance is the natural byproduct of their privilege; they cannot see the connections between their servants because they do not truly see the servants at all, treating them as interchangeable parts of a domestic machine.■
