I thought I was writing a period piece about the 1980s in America. Not for a moment did I suspect that the financial 1980s would last two full decades longer or that the difference in degree between Wall Street and ordinary life would swell into a difference in kind. I expected readers of the future to be outraged that back in 1986, the C.E.O. of Salomon Brothers, John Gutfreund, was paid $3.1 million; I expected them to gape in horror when I reported that one of our traders, Howie Rubin, had moved to Merrill Lynch, where he lost $250 million; I assumed they'd be shocked to learn that a Wall Street C.E.O. had only the vaguest idea of the risks his traders were running. What I didn't expect was that any future reader would look on my experience and say, "How quaint."

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.

Great. Chilling.

Capitalism searches out the darkest corners of human potential, and mainlines them.
