In "Liar's Poker," Michael Lewis explores the culture of investment banking, highlighting the unspoken rules that govern conversations in the industry. One significant taboo is the avoidance of discussing financial motivations openly. When aspiring bankers are asked about their career choices, they are expected to emphasize the prestige and excitement associated with the job, rather than openly admitting that the allure of money is a primary factor.

This cultural norm reflects a broader expectation within the financial services industry, where showcasing ambition and strategic thinking takes precedence over financial gain. By noting this contradiction, Lewis sheds light on the complexities of the banking world, where reality often contradicts the façade that individuals are compelled to maintain.
