Ballard's short story "Billenium" depicts a dystopian future where overpopulation has led to extreme crowding. The main characters, Ward and Rossiter, discover a hidden room that could offer them more space and freedom. However, they are unable to escape the social norms of their capitalist society and consumerist mindset. They fill the new room with furniture and invite others to move in, returning to the same cramped conditions they previously endured. The discovery of new space ultimately changes nothing due to the overwhelming social and economic forces that condition people's lives in this overpopulated city.
