Wealth Flight Concern

California voters will decide on Proposition 40, a 5 % tax on residents with net worth over $1 billion, on Nov. 3, 2026 ballot.
Governor Gavin Newsom opposes the billionaire tax and backs Proposition 42, saying it protects firefighters, unions, veterans, seniors and small businesses.
Opponents warn the tax could drive wealthy industry leaders out of California, hurting the economy.
SEIU-UHW supports the tax, allocating 90% to healthcare and 10% to education and food aid.

Blindspot

Union leader Dave Regan and economists Emmanuel Saez, David Gamage, Darien Shanske, and Brian Galle say Proposition 40 would generate about $100 billion in one-time revenue for California’s health, education and food-assistance programs.
Within this story's sources, this angle appears mainly in Left-leaning coverage and receives less attention in Right-leaning coverage.

History

Historical Context

In 2019, Senators Elizabeth Warren and Bernie Sanders introduced the Ultra-Millionaire Tax, a federal 2 % levy on fortunes above $50 billion, which failed to pass. The proposal projected $2.75 trillion in revenue over ten years, according to the Treasury Department’s analysis, sparking intense debate among economists like Emmanuel Saez. California’s Proposition 40, championed by Governor Gavin Newsom’s opponent Dave Regan and backed by SEIU-UHW, mirrors that wealth-tax ambition by targeting billionaires for a 5 % levy. If passed, the measure could generate roughly $100 billion, echoing the earlier federal estimate and reshaping California’s fiscal landscape for health, education, and food aid.
