Renowned economist Gabriel Zucman released a blueprint Tuesday showing the world's governments that a global minimum tax on billionaires would be both technically feasible and economically beneficial, leaving political will as the only major obstacle preventing transformative changes to an international tax structure long exploited by the ultra-rich. A 2% minimum tax on the wealth of global billionaires would raise between $200 billion and $250 billion annually in revenue from roughly 3,000 individuals globally, resources that "could be invested to support sustained economic development through investments in education, health, public infrastructure, the energy transition, and climate change mitigation." Billionaires ... pay lower effective income tax rates than those in the working class, often making use of holding companies and other complex maneuvers to dodge their obligations and stockpile massive fortunes. The world's billionaires collectively own $14.2 trillion in wealth. Structuring a new tax based on a specific percentage of billionaires' wealth would prevent ultra-rich individuals who report little to no taxable income from completely avoiding taxation. The primary barrier to establishing a global tax on billionaires is not technical, Zucman argued, but political, particularly given the sway the ultra-rich have over economic policy. A YouGov poll ... found that 59% of U.S. millionaires would support a global tax on billionaires equal to 2% of their wealth.
