Summary

Economist Gabriel Zucman argues that taxing billionaires is necessary to address rising inequality and growing government debt worldwide. For over 15 years, Zucman has studied how the wealthy use tactics such as offshore tax havens to avoid paying taxes, and now advocates for a wealth tax to bring billionaires into the income tax fold. According to him, if France's billionaires were to flee to the Cayman Islands, it would result in a loss of 0.03% of tax revenue, making them not a significant concern. Zucman believes that taxing billionaires is essential to completing the unfinished revolution of democracy and upholding equality before the law.

Story summary

Gabriel Zucman, an economist who teaches at Berkeley, has spent over 15 years studying the world's wealthiest individuals and their tactics for avoiding taxes. He has analyzed how they use countries like Luxembourg and the British Virgin Islands to evade taxation. At just 21 years old, he was already researching international financial transactions and discovering hidden money in offshore tax havens. This research gained widespread attention with the release of the Panama Papers in the mid-2010s. Zucman is now advocating for a wealth tax on billionaires, citing his own findings that even if all French billionaires were to relocate to the Cayman Islands, the loss of tax revenue would be only about 0.03%. He argues that taxing the wealthy is necessary due to extreme levels of inequality worldwide.
