California proposes one‑time 5% wealth tax on billionaires

A statewide ballot measure slated for the November 3 election would amend the California constitution and create a statute imposing a one‑time 5 percent tax on the accumulated wealth of the state’s billionaires. The initiative, championed by the SEIU United Healthcare Workers West union, is intended to fund state‑run health‑care programs. Economists such as Emmanuel Saez and Gabriel Zucman have argued the tax is a matter of fairness, while critics contend it may deter investment, lower productivity growth and ultimately hurt workers.

Billionaires, including Google co‑founder Sergey Brin, have mounted a vigorous opposition, spending tens of millions of dollars to defeat the measure and warning they may relocate out of California if it passes. The debate centers on whether the tax will generate significant revenue or simply shift future tax expectations and affect the state’s economic climate.
