Probably true. But I'm reminded that when Michael Lewis wrote his first book, 'Liar's Poker', he viewed it as a cautionary tale and a polemic against the behaviors he saw on Wall Street. He was surprised that its readers took it more as an instruction manual and an invitation to participate.

EDIT: Found the link to the interview I'm misquoting. Here's the original passage:

"I had no great agenda, apart from telling what I took to be a remarkable tale, but if you got a few drinks in me and then asked what effect I thought my book would have on the world, I might have said something like, “I hope that college students trying to figure out what to do with their lives will read it and decide that it’s silly to phony it up and abandon their passions to become financiers.” I hoped that some bright kid at, say, Ohio State University who really wanted to be an oceanographer would read my book, spurn the offer from Morgan Stanley, and set out to sea.

Somehow that message failed to come across. Six months after Liar’s Poker was published, I was knee-deep in letters from students at Ohio State who wanted to know if I had any other secrets to share about Wall Street. They’d read my book as a how-to manual."
