A ‘wealth tax’ presents a revenue estimation puzzle. Lawrence Summers, April 4, 2019, Opinion,“Sen. Elizabeth Warren (D-Mass.) recently proposed a 2 percent “wealth tax” on those worth more than $50 million. Emmanuel Saez and Gabriel Zucman, economists at the University of California at Berkeley, have played a major role in developing and validating this proposal. They estimate that the tax would raise $187 billion in 2019 (Warren’s additional 1 percent “billionaire surcharge” brings their total revenue estimate to $212 billion). This represents a substantial sum and has been widely quoted in both academic and policy discussions of wealth taxation.Link
