The Big Short by Michael Lewis. Twenty years ago he wrote Liar's Poker as, he tells us, a warning to his peers to avoid investment banking, and do something useful like marine biology or poetry.
Instead, his peers and younger folks found an even scummier way to scam the poor: Sub-prime mortgages. Interestingly, this book is about the dozen or so people who saw the current Depression coming, figured out how to make money from it, screamed to anyone who would listen what was happening, and, when they saw no one listening, went short.
Interestingly, they are almost all social misfits, including one Asberger's sufferer.
And even more interesting, the Asberger's sufferer tipped off Goldman, Sachs to what was happening. He did this in 2002, before Henry Poulson was known outside of Wall Street.
