In brief
California’s November ballot will determine whether a one‑time 5 % wealth tax on residents netting over $1 bn is enacted. The proposal, named Proposition 40, aims to raise $100 bn to offset federal cuts to the state’s health‑care system. Supporters argue it levels the playing field; opponents warn it will drive billionaires out and hurt the economy. So far, twelve of the more than 200 billionaires in California have moved elsewhere to avoid the tax. The vote could set a precedent for similar measures elsewhere in the U.S.
California, home to some 200 billionaires, is poised to hold a referendum that could impose a 5 % one‑time tax on the net worth of residents exceeding $1 bn. The measure, called Proposition 40, would raise roughly $100 bn to cover cuts to the state’s health‑care system amid federal budget reductions.
Proponents claim the tax corrects extreme inequality, noting that 72 % of Californians feel the rich‑poor gap is widening. They also cite concerns that the wealthy are increasingly shaping policy without sharing the benefits that fund essential services.
Opposition is fierce. Governor Gavin Newsom warned the tax could trigger a capital flight, taking jobs and revenue out of the state. Several billionaires—Mark Zuckerberg, Nvidia CEO Jensen Huang, and former Silicon Valley founders Larry Page and Sergey Brin—have announced moves to Nevada or other jurisdictions to avoid the levy. The businessman Don Hankey said he left California because he felt “not wanted.”
Supporters include public‑policy professor Francesco Trebbi of UC Berkeley, who sees the measure as a “rebalance the scale” effort. Senator Bernie Sanders of Vermont has campaigned in favor, arguing that billionaires should share the burden that keeps the state’s infrastructure running.
The measure’s passage would make California the first jurisdiction worldwide to tax the very wealthiest, potentially influencing other states such as Washington that are debating “millionaire taxes.” Analysts warn that wealth taxes can drive capital out and suppress investment, yet the urgency of California’s health‑care funding needs has amplified support for Proposition 40.
The vote will be decided by a simple majority of eligible voters on November 3. Polls as of September show 45 % in favor, 42 % opposed, and 13 % undecided. Only a majority will carry the bill to enact a historic wealth tax on the globe’s richest residents.
