The central conflict in Look What You Made Me Do is deeply rooted in the economic tensions and resentments that define the relationship between the property-rich baby boomer generation and a more financially precarious millennial generation. The novel frames the personal vendetta between Phoebe and Kate as a skirmish in a wider intergenerational war fueled by stark disparities in wealth and opportunity. Phoebe’s animosity toward Kate and Jack is explicitly linked to her perception of their “complacent affluence,” a lifestyle built on unearned housing wealth and economic good fortune. Through this lens, Lanchester suggests that personal animosities are often inseparable from, and inflamed by, broader class and generational anxieties, particularly in a city like London where property has become the ultimate marker of success and security.

The novel establishes the boomer perspective through a dinner party where Jack and his architect friends, Michael and Tanya, casually discuss the state of the London property market. Jack notes that his clients are now almost exclusively wealthy foreigners who see British property as accessible due to a weak pound after Brexit. They are the clear beneficiaries of a system that treats housing as a global commodity rather than a social good. Their conversation reveals an awareness of this economic reality but also a detached acceptance of it, as it directly fuels their professional success. This casual entitlement is precisely what younger characters perceive as an unearned and galling privilege, leading to the conflict to come.

This sense of injustice is articulated most clearly through the character of Katrina, a millennial journalist at the same dinner party. While outwardly polite, her inner thoughts reveal a simmering resentment. Kate observes on Katrina’s face a “startling weariness, even a contempt,” (15) which she interprets as an expression of “intergenerational dislike.” Kate imagines Katrina sees the older generation as having “cruised through life sitting on the great sofa of baby boomer entitlement and economic good fortune” (15). This moment makes the subtext of the novel explicit, framing the personal dynamics of the evening as a microcosm of a larger societal antagonism. Phoebe’s later actions are driven by a similar sense of inherited grievance; she seeks to dismantle the comfortable world of a generation she believes wronged her mother and holds an unfair advantage in life.

The material emblems of this divide, particularly housing, are ever-present. Michael and Tanya’s home is a massive, converted double-terrace house that Kate deems “Architectural Digest vulgar,” (7) functioning more as a “showroom” for their success than a home. Similarly, Kate and Jack’s technologically advanced house is proof of their wealth. In contrast, Phoebe’s mother lives in a “gloomy basement” flat in Earl’s Court, a physically and emotionally oppressive space despite its high monetary value. This contrast emphasizes the material disparities that fuel the conflict, suggesting that Phoebe’s revenge is an attack on the very symbols of the economic system that she feels has left her and her generation behind.
