Why do billionaires pay less tax than you? Billionaires often pay a lower income tax rate than nurses, teachers and almost everyone else - sometimes close to zero. This isn't tax evasion, it's the system. In this explosive manifesto, Gabriel Zucman - the economist revolutionising the study of inequality - reveals how the ultra-rich dodge billions using havens, loopholes and political influence, while public services are breaking. Until we understand the hidden rules that protect extreme wealth, inequality will keep rising and democracy will keep losing. This game-changing book finally shows us how making the ultra-rich pay their fair share is possible, and why now is the moment.
