Prop 40

California
billionaire tax

Keep Hospitals & ERs Open

We’re calling on California’s billionaires to pay a one-time, 5% emergency billionaire tax to prevent the collapse of California healthcare and ensure our state’s families can get the care we need. Prop 40 is a common sense solution to a looming crisis and will help our state build a strong middle class.

Massive federal healthcare cuts are driving California towards a healthcare collapse

Deep federal cuts strip roughly $100 billion from California healthcare over the next five years—pushing our state toward a healthcare collapse that hurts California families. Insurance premiums will go up for everyone, and millions of Californians will lose coverage altogether. Local hospitals, clinics, and nursing homes, home care services that we rely on will cut services or close. Skeleton crews will be left on the front lines as 145,000 healthcare jobs disappear, burning out the people who care for our families. Prop 40 is a common sense solution to stop the healthcare collapse.

OUR SOLUTION: PROP 40 - THE CALIFORNIA BILLIONAIRE TAX ACT:
A one-time, 5% emergency billionaire tax

THE BIG PICTURE:

prop 40 can stop the healthcare collapse

The wealth of U.S. and California billionaires has grown enormously over the past decades — much faster than overall economic growth. In 1982, the wealth of the top .0002% Americans was about 2% of the country’s GDP (gross domestic product). In 2025, it has increased to 20% of GDP. From 1982 to 2025 the annual growth of billionaire’s wealth has been 7.5% per year, five times the growth of average incomes over the same period (1.5% per year).
