The main theme of the book is that those who have “skin in the game” – a personal stake in the outcome – are more likely to act in the best interests of society and make better decisions. Taleb argues that people who have skin in the game are more reliable and trustworthy because they have a personal stake in the outcome.
He also discusses how this concept applies to a variety of fields, including economics, politics, and social justice. Throughout the book, Taleb uses examples and anecdotes to illustrate his points, and he advocates for a more fair and just society where everyone has skin in the game.
