Same thing happened with Michael Lewis's Liar's Poker [1]. Written as a parody. Now distributed to junior bankers as a handbook of hustle and an advertisement of the good life promised.
To quote from the Wikipedia article: "semi-autobiographical book [...] describing the author's experiences as a bond salesman on Wall Street during the late 1980s".
Before reading Liar's Poker I was ignorant about, and extremely hostile to the financial industry, and the book brought about complete change. The book is at best ambivalent about high finance, but clearly also glamourises the industry.
