Zucman argues that inequality is not just a side effect of capitalism, but it is a policy choice. He shows how tax systems have been reshaped to benefit the ultra-rich, with billionaires now paying less tax than middle class workers. His core message is blunt, if we want to fix inequality, we need to fix the tax system. That means progressive income taxes, a serious wealth tax, and cracking down on tax havens. He is not just talking theory, but he lays out practical steps, backed by hard data, to make the rich pay their fair share. Zucman’s vision is global: coordinated action across countries to stop the race to the bottom and start and race to the top.
