The other side says the category is a cash grab "on average," but that quietly gives up the real claim. The question is whether these memoirs are just cash grabs, and if even my opponent admits some carry real literary value, then "just" falls apart. Besides, the incentive argument proves too much: thrillers, cookbooks, and pop albums are also low-risk products built to sell. A commercial motive doesn't make the work empty. Readers aren't marks. A lot of them finish a memoir and genuinely get something out of it, and that's what should decide this.
