Foundations of a Free Society argues that freedom is the driving force behind prosperity, innovation, and wealth creation. Free societies are more economically equal, with the poor benefiting the most from economic dynamism. Government’s role is limited to enforcing justice, ensuring equality under the law, and protecting peaceful cooperation. Attempts to equalize wealth through government intervention harm incentives and productivity. The book emphasizes the importance of tolerance, free expression, and open communication in fostering progress, while highlighting the global spread of freedom through trade and technology.
