Think you’ll never understand the Wall Street mess? Read this, and think again.

Michael Lewis, author of Liar’s Poker, has a story at Portfolio.com that is a must read for anyone interested in getting a down-and-dirty view of the Wall Street methods that helped create the housing bubble and/or mortgage mess.

What’s more, Lewis’ piece is fast-paced, with interesting vignettes about interesting people and written in a non-financial language we all can understand.

Excerpts from Lewis’ piece include:

“Then came Meredith Whitney with news. Whitney was an obscure analyst of financial firms for Oppenheimer Securities who, on October 31, 2007, ceased to be obscure. On that day, she predicted that Citigroup had so mismanaged its affairs that it would need to slash its dividend or go bust. It’s never entirely clear on any given day what causes what in the stock market, but it was pretty obvious that on October 31, Meredith Whitney caused the market in financial stocks to crash. By the end of the trading day, a woman whom basically no one had ever heard of had shaved $369 billion off the value of financial firms in the market. Four days later, Citigroup’s C.E.O., Chuck Prince, resigned. In January, Citigroup slashed its dividend.”

“Now, obviously, Meredith Whitney didn’t sink Wall Street. She just expressed most clearly and loudly a view that was, in retrospect, far more seditious to the financial order than, say, Eliot Spitzer’s campaign against Wall Street corruption. If mere scandal could have destroyed the big Wall Street investment banks, they’d have vanished long ago. This woman wasn’t saying that Wall Street bankers were corrupt. She was saying they were stupid. These people whose job it was to allocate capital apparently didn’t even know how to manage their own.”
