Gabriel Zucman has developed a high profile creating new data on tax systems, tax havens and inequality. To coincide with the release of his new book The Triumph of Injustice: How the rich dodge taxes and how to make them pay, he has launched a new, user-friendly website, Tax Justice Now. It’s focused on the tax system in the United States, and it starts with:
America’s runaway inequality has an engine: our unjust tax system
This statement is not without controversy: other explanations for inequality include the rise (especially in the United States) of monopoly and market power: an enormous issue that intersects with tax justice, as we will soon explain. Nevertheless, Zucman’s site is immensely useful, and contains some marvels. Here are a couple:
The site also allows you to design your own tax system (up to a limited point), adjusting sliders and tax rates and so on, to project the effect of reform on particular billionaires. You can also look at the effects of adjusting the total tax rate on corporations combining state and federal taxes.
Overall, another useful resource.
