California faces mounting challenges in its healthcare system as costs rise, workforce shortages persist, and federal and state budget reductions threaten services for millions of residents. Against this backdrop, Proposition 40, a measure set for the November 3 ballot, proposes a one-time tax on billionaire wealth aimed at generating billions for the state’s Medicaid program, Medi-Cal. However, critics caution that the initiative lacks necessary safeguards and clarity on how the funds would be managed and allocated.
Proposition 40 is designed to address cuts to federal funding and provide financial support to Medi-Cal, which covers healthcare for millions of low-income Californians. More than 90% of Medi-Cal enrollees receive care through managed care plans, most of which are operated by private health insurance companies. These plans account for nearly 70% of total Medi-Cal spending, with health insurers receiving per capita payments that include profit margins.
Despite the stated goal of easing pressures on Medi-Cal, opponents argue that the proposition leaves insurance companies poised to gain substantial additional revenue without sufficient accountability measures. The language of the initiative permits the funds to be used for a wide range of purposes, including "addressing reductions in federal funding, supporting health coverage programs, preventing facility closures, and making payments to providers." However, none of these uses are explicitly mandated, raising concerns that the money could simply increase insurer profits rather than improve patient care or reduce costs.
The proposition includes a clause stating that the funds cannot replace existing state funding, but critics contend this provision lacks the rigorous protections necessary to prevent budgetary shifts. Past propositions, such as the 2016 tobacco tax (Proposition 56) and the 2024 measure imposing a permanent tax on managed healthcare plans (Proposition 35), included stricter language intended to ensure new funds supplemented rather than supplanted existing expenditures. Nonetheless, critics note that state officials have previously redirected funds for other purposes despite these requirements.
Jennifer Kent, former director of the California Department of Health Care Services, emphasized that the absence of clear mechanisms to guarantee additional healthcare spending or higher reimbursement rates for providers undermines the proposition’s potential effectiveness. She characterized Proposition 40 as lacking the enforceable spending mandates, transparent oversight, and accountability that are essential to addressing the systemic issues facing California’s healthcare system.
Supporters of Proposition 40 highlight the urgent needs within Medi-Cal and the broader healthcare system, while critics urge voters to consider whether the measure will produce tangible benefits for patients and providers or simply bolster insurance company profits. Many experts argue that California requires durable reforms that strengthen patient protections, stabilize support for providers, and enhance workforce capacity, all backed by clear enforcement and oversight.
As voters prepare to decide on Proposition 40, the debate centers on whether the initiative offers a meaningful solution to the state’s healthcare funding crisis or risks delaying more substantive changes needed to improve access and quality of care.
