In Michael Lewis's book "Liar's Poker," he presents a metaphor comparing the process of making profits on Wall Street to eating stuffing from a turkey. He suggests that before one can make money, there must be a source that provides the necessary resources or capital. This indicates that the ability to profit relies heavily on external factors.

Lewis points out that during the 1980s, the financial environment was particularly favorable, as there was a significant influx of capital or "stuffing" available for those seeking profits. The decade is characterized by generous financial opportunities, highlighting how market conditions can impact the potential for earning on Wall Street.
