"The Social Contract" is a philosophical work that discusses the concepts of sovereignty and the social contract. The author argues that all men are born free, but everywhere they are in chains, suggesting that society and its rules are a form of enslavement. However, he also posits that a social contract, where individuals come together to form a collective or a society, is necessary for the preservation of their freedom. This contract allows for the creation of a sovereign that is made up of the collective and expresses the general will, which is always right and tends towards the public utility.

This book provides a comprehensive analysis of the dynamics of capital accumulation and distribution over the last few centuries. The author argues that the rate of capital return in developed countries is persistently greater than the rate of economic growth, leading to high levels of wealth inequality. The book further suggests that the level of income inequality is not primarily a result of differences in individual labor income but rather the result of differences in capital ownership and the income derived from it. The author proposes a global tax on wealth to prevent soaring inequality.
