The quote highlights how the character's dissatisfaction with life stems from interactions with others. It suggests that external relationships can be a significant source of discontent, implying that the challenges one faces are often tied to the behavior and decisions of those around them. This reflects a common theme in literature where personal struggles are exacerbated by societal dynamics.

In Michael Lewis's "The Big Short: Inside the Doomsday Machine," this notion emphasizes the impact of human actions within the financial world. The characters navigate a maze of greed and irresponsibility, where their unhappiness is not merely an individual experience but is influenced by the systemic flaws and behaviors of their peers in the economic landscape.
