California voters to decide on first-in-the-world wealth tax on billionaires

California voters will decide on Proposition 40, a measure to impose a one-time 5% tax on the net worth of the state's billionaires. The tax aims to raise $100 billion to offset federal healthcare funding cuts. With over 200 billionaires in the state, including Oprah Winfrey and Mark Zuckerberg, the measure has sparked debate over wealth inequality and healthcare funding.
