Andrew Ross Sorkin's book, '1929: The Inside Story of the Greatest Crash in Wall Street History,' examines the mindset and market conditions that led to the 1929 crash. The book explores beliefs in self-correcting markets, leverage as innovation, and perpetual good times, highlighting an era of abundant credit and normalized speculation. Sorkin details how easy credit and minimal oversight fostered a system rewarding speed and secrecy, with manipulative stock pools artificially inflating prices and drawing in small investors.
