Let's frame this honestly. A celebrity memoir isn't a book that happens to have a famous author; it's a product built around an existing brand. Publishers pay huge advances because the fanbase guarantees sales, not because the writing is good. Most are ghostwritten, rushed to hit a news cycle, and forgotten in a year. That's merchandising, not literature. My opponent may point to a few genuine exceptions, but the genre's economic logic is what matters. When the money comes first, the memoir is the cash grab.
