In "Steering Clear," published in 2015, Peterson makes the case that we need to take immediate action to reduce long-term debt in the US, projected to hit record highs in the near future.

'Fooling Some of the People All of the Time' by David Einhorn

In this book, Einhorn tells his side of a six-year financial saga.

Here's the short version:. In 2002, Einhorn, founder of Greenlight Capital, thought he'd uncovered flawed accounting practices at Allied Capital and started short selling Allied's stock. That didn't work, as the stock climbed. Einhorn tried to expose Allied's unethical behavior, even approaching the US Securities and Exchange Commission, but the SEC ended up investigating him as well. Ultimately, Allied settled with the SEC in 2008 and the accusations were never substantiated.

The book is heavy on detail, and one critic says that some parts read like Einhorn's angry rant. But it nonetheless offers some compelling insights into the general drama that often unfolds on Wall Street.
