LOS ANGELES, Nov 10 — California voters have rejected a one-time tax on billionaires, US media projected yesterday, despite growing anger over global wealth disparity.

The tax would have forced around 200 billionaires in the state to cough up five per cent of their total net worth, with the money largely dedicated to helping pay for healthcare.

CNN and CBS News both projected that so-called Proposition 40 would not pass, nearly a week after voters cast ballots on whether to tax the billionaires.

With the highest population of any US state, California is notoriously slow at counting votes.
