This chapter analyzes the interplay between fantasy, nostalgia, and capitalism through the lens of science fiction and popular culture. Using examples from Star Trek, fantasy literature, and psychoanalytic theory, it explores how speculative fiction and genre narratives construct worlds that both reflect and shape cultural desires for authenticity, stability, and meaning. The chapter argues that both fantasy and capitalism operate by promising satisfaction through repetition and deferral, transforming lack and failure into engines of desire. Drawing on Lacanian insights into desire and the structures of discourse along with insights from theorists such as Todd McGowan, Stijn Vanheule, and Alenka Zupančič, it contends that the commodification of nostalgia and the endless cycles of consumerism mirror the narrative structures of fantasy, where fulfillment is always postponed and the present is haunted by both past and future.
