Bloomberg Businessweek, The Wealth Detective Who Finds the Hidden Money of the Super Rich:
Thirty-two-year-old French economist Gabriel Zucman scours spreadsheets to find secret offshore accounts.
Zucman, 32, is an assistant professor at the University of California at Berkeley and the world’s foremost expert on where the wealthy hide their money. His doctoral thesis, advised by Piketty, exposed trillions of dollars’ worth of tax evasion by the global rich. For his most influential work, he teamed up with his Berkeley colleague Emmanuel Saez, a fellow Frenchman and Piketty collaborator. Their 2016 paper, “Wealth Inequality in the United States Since 1913,” distilled a century of data to answer one of modern capitalism’s murkiest mysteries: How rich are the rich in the world’s wealthiest nation? The answer—far richer than previously imagined—thrust the pair deep into the American debate over inequality. Their data became the heart of Vermont Senator Bernie Sanders’s stump speech, recited to the outrage of his supporters during the 2016 Democratic presidential primary.
Zucman and Saez’s latest estimates show that the top 0.1% of taxpayers—about 170,000 families in a country of 330 million people—control 20% of American wealth, the highest share since 1929. The top 1% control 39% of U.S. wealth, and the bottom 90% have only 26%. The bottom half of Americans combined have a negative net worth. The shift in wealth concentration over time charts as a U, dropping rapidly through the Great Depression and World War II, staying low through the 1960s and ’70s, and surging after the ’80s as middle-class wealth rolled in the opposite direction. Zucman has also found that multinational corporations move 40% of their foreign profits, about $600 billion a year, out of the countries where their money was made and into lower-tax jurisdictions.

Like many economists, Zucman and Saez have embraced the political implications of their research. Unlike many, they champion policy recommendations that are bold and aggressive. Before Massachusetts Senator Elizabeth Warren started her 2020 presidential campaign by proposing a wealth tax, she consulted the pair, who estimated that her tax would bring in $2.8 trillion over the next decade. She conferred with them again before floating a corporate tax on profits above $100 million, which they calculated would raise more than $1 trillion over 10 years. Sanders came looking for their advice on his estate tax plan, which would establish rates as high as 77% on billionaires. And when New York Representative Alexandria Ocasio-Cortez proposed on 60 Minutes to hike the top marginal tax rate to as much as 70% on income above $10 million, Zucman and Saez were fast out with a New York Times op-ed in support.
The pair has now written a cookbook of sorts for any 2020 candidate looking to soak the rich. The Triumph of Injustice, to be published by W.W. Norton & Co. early next year, focuses on how wealth disparity can be fought with tax policy. The tools Zucman has identified to date challenge a series of assumptions, fiercely held by many economists and policymakers, about how the world works: That unfettered globalization is a win-win proposition. That low taxes stimulate growth. That billionaires, and the superprofitable companies they found, are proof capitalism works. For Zucman, the evidence suggests otherwise. And without taking action, he argues, we risk an economic and political backlash far more destabilizing than the financial crisis that sparked his work.
