In the novel "American Psycho" by Bret Easton Ellis, there’s a notable mention of Donald Trump's admiration for the rock band U2, highlighting a playful connection between pop culture and the elite. This detail not only adds to the characterization within the story but also reflects the characters' obsession with status and celebrity in the 1980s.

Additionally, the mention of John Gutfreund purchasing U2 records suggests a desperate attempt to align himself with cultural trends, further illustrating the theme of superficiality in the lives of the wealthy characters. It emphasizes how their identities are often shaped by material possessions and social perceptions.
