Universal healthcare cost estimates: my policy research lessons

Green Mountain Care, authorized three years earlier through Act 48, was meant to become the nation’s first state-level single-payer system. It never treated a single patient.

Its projected first-year cost was $4.3 billion. To finance it, Vermont would have needed a dramatic increase in state tax collections—estimated at 151% to 160% in the first year. The political math failed before the policy reached the clinic door.

That history matters whenever someone asks how much will universal healthcare cost. The question is often framed as though universal coverage introduces a new expense into an otherwise affordable system. It does not. The United States already pays for healthcare through premiums, payroll deductions, deductibles, co-pays, public programs, employer contributions, debt, and foregone care that turns into more expensive care later. Single payer changes the collection mechanism. It makes costs visible that private insurance has spent decades scattering across paychecks and household budgets.

Vermont’s failure is not proof that universal healthcare is unaffordable. It is proof that a state trying to build a universal system inside a federal financing structure faces constraints that rhetoric cannot wish away.

The Green Mountain Ambition and the 94% Coverage Standard

The original Green Mountain Care design, drafted by Harvard economist William Hsiao, proposed a 14.2% payroll tax: 10.6% paid by employers and 3.6% paid by employees. That structure was intended to fund a plan with an 87% actuarial value.

Actuarial value is dry language for a very real question: how much of a person’s covered healthcare spending is paid by the plan, rather than pushed back onto the patient through deductibles, co-pays, and other out-of-pocket costs. An 87% actuarial value would already have represented substantially stronger coverage than many people receive through ordinary employer insurance.

But the policy did not remain fixed at its original design. Pressure from hospitals, labor, patient advocates, and other constituencies helped move the benefit structure toward a 94% actuarial value. Coverage was also extended to out-of-state commuters. The higher actuarial value increased projected costs. That is the essential point—not because generosity is an error, but because benefit design and financing have to be built together.

This is where discussions of Medicare for All cost projections regularly become evasive. One side treats benefits as if they can expand without a fiscal consequence. The other treats every public expenditure as a fresh burden, even where it replaces premiums and medical bills people already pay. Both moves obscure the actual political choice.

A universal plan can be less costly to households while requiring more visible public revenue. It can also be made more generous in ways that increase the amount a public authority must collect. Those propositions are not contradictory. They are the terrain of the fight.

Vermont’s legislators were not irrational to seek robust coverage. A universal system that leaves people underinsured has simply nationalized a thinner version of private insurance. But a state cannot promise near-comprehensive coverage, rely on a limited tax base, and then pretend the funding question is merely technical.

A generous benefit package is a political commitment. It has to be matched by an equally serious commitment about who pays.

The lesson is not that the 94% standard was too humane. The lesson is that the financing model needed to be credible at the same scale as the benefits. That is true for Vermont, Oregon, and any future federal program.

Dissecting the $4.3 Billion Price Tag of State-Level Single Payer

The projected first-year cost of Green Mountain Care was $4.3 billion. Vermont’s entire state budget for fiscal year 2012–2013 was $5.01 billion. Put next to one another, those figures make the proposal look almost absurd: a healthcare plan approaching the scale of the whole machinery of state government.

But this is also where the headline number can mislead.

The cost of a single payer healthcare system is not identical to a new cost imposed on society. Green Mountain Care was designed to replace a fragmented collection of payments: private premiums, employer contributions, household out-of-pocket spending, and existing public healthcare expenditures. The state would have collected more money because it would have been taking responsibility for payments that were previously hidden in business budgets, insurance invoices, and family finances.

That distinction matters, although it does not make the $4.3 billion figure disappear. A state government still needs the cash flow. It still has to collect revenue on time, pay providers on time, and keep the system operating through downturns, enrollment changes, and federal policy shifts. “We already spend this money” is not, by itself, a financing plan.

The difference between private spending and public spending can be laid out plainly:

The problem was not simply that Green Mountain Care had a large price tag. The problem was that the price tag landed on Vermont’s state ledger all at once. Private premiums feel like a workplace norm. An income-tax increase appears as a government decision, even if it replaces an insurance payment that was already draining a household.

That visibility gap is one reason funding universal healthcare in the US is politically harder than the aggregate economics suggest. People are trained to see taxes as a loss and premiums as an unavoidable fact of employment. The employer contribution is treated as though it materializes from nowhere. The deductible is treated as personal responsibility. The medical debt is treated as bad luck. A public system gathers those scattered obligations into one visible mechanism—and suddenly the political class calls it unaffordable.

The Shumlin administration’s later analysis projected 1.6% savings in overall healthcare costs over three years for the final, more expensive version of Green Mountain Care. Earlier projections had anticipated much larger long-term savings. The point is not to manufacture a tidy numerical comparison between them. The point is that the projected savings narrowed as the final plan became more expensive and the practical limits of state-level financing became clearer.

That is not a reason to dismiss public provision. It is a warning against selling universal care as a magic trick. Administrative savings matter. Better purchasing power matters. Reduced billing complexity matters. But a reform’s savings are shaped by its benefits, its payment rates, its federal arrangements, and the economy in which it is trying to operate.

The Tax Transition Hurdle: From Premiums to Payroll Levies

The hardest part of a single-payer transition is not proving that the country spends too much on healthcare. That case has been made repeatedly. The hard part is moving money from a fragmented private system into a public one without making working people, small employers, or vulnerable communities carry the shock.

The existing system is financed through employer-sponsored premiums, employee payroll deductions, out-of-pocket payments, Medicare, Medicaid, ACA subsidies, and a long list of subsidies and tax preferences. A universal system would replace much of that patchwork with public revenue. The transition must be substitutive, not additive. If people keep paying their old premiums and then face a new healthcare tax on top, the reform has failed on its own terms.

Vermont’s proposed funding structure was built around the following sources:

The proposed 11.5% employer payroll tax was often discussed as a replacement for the employer share of private insurance premiums. For firms already offering relatively comprehensive coverage, that could look close to a substitution. For employers offering less coverage, employing lower-wage workers, or relying on precarious work, it could look like a substantial new obligation.

That is not an argument for preserving an employment-based insurance system that leaves workers tied to a job for their care. It is an argument for designing the transition honestly. A payroll levy can be progressive or regressive depending on its structure. An income tax can protect lower-income residents or punish them. Exemptions can shield small businesses, or they can create holes that force everyone else to pay more. These choices are not footnotes to policy design. They are the policy design.

The individual tax component was especially politically exposed because it was direct and legible. People can compare a new income-tax line with their current take-home pay. They do not always see the employer premium contribution that suppresses wages, or the premium increase negotiated behind closed doors, or the deductible waiting for them when they get sick.

This is the tax transition hurdle in its clearest form:

1. Show what disappears. A credible plan must identify which premium payments, deductibles, and employer costs are being replaced—not merely announce a new tax rate.

2. Protect workers during conversion. Employers should not be allowed to pocket savings from eliminated premiums while workers absorb the new public contribution.

3. Build progressivity into the revenue model. The people who have benefited most from the current system’s inequities cannot be allowed to offload the transition onto low-wage labor.

4. Plan for cross-border pressure. A single state has to consider employers, commuters, and neighboring jurisdictions in ways a federal program does not.

5. Say plainly what remains uncertain. A plan dependent on federal cooperation should not present that cooperation as guaranteed revenue.

Vermont’s proposed tax increase was politically explosive because the state was trying to raise enough public revenue to replace a large share of privately mediated spending. Calling that merely a tax hike missed the substitution. Calling it painless would have been just as dishonest.

Navigating the $300 Million Federal Funding Shortfall

Vermont faced a projected $300 million shortfall in expected federal funding: $150 million less in federal program funds and $150 million less in federal Medicaid funds than the plan had assumed. This was not just a state budgeting problem. It exposed the central weakness of state-level single payer.

Federal healthcare dollars arrive through programs with their own rules, eligibility categories, administrative requirements, and political constituencies. Medicaid is not a blank check. Medicare is not controlled by state legislatures. ACA subsidies, employer tax exclusions, and drug-pricing rules are all embedded in federal law.

Vermont sought a waiver that would have given it more flexibility to redirect federal funding into a unified system. The Obama administration did not grant it. That left the state attempting to construct a broad public financing system while major streams of healthcare funding remained outside its control.

The federal shortfall was therefore more than a painful line in a fiscal model. It represented a boundary of authority. Vermont could pass Act 48. It could design benefits. It could propose taxes. But it could not simply command federal healthcare dollars to flow through a new state payment system.

This is the point that gets lost when critics treat Vermont as a morality tale about government failure. The state was not operating in a vacuum. It was trying to reorganize healthcare financing beneath a federal framework designed around separate programs, private insurance, and employer-linked coverage.

A state can improve coverage. It can regulate insurers. It can expand eligibility. It can strengthen public options and negotiate more aggressively. What it cannot easily do is consolidate the full financing architecture without federal permission.

A state can design a universal system on paper. Federal law decides how much of the money can actually enter the room.

That does not mean state action is useless. State campaigns build institutions, train organizers, create policy expertise, and make the demand for federal reform more concrete. But they should not be asked to carry alone what is fundamentally a national obligation.

Oregon’s 2026 Roadmap: Applying the Lessons of Act 48

Oregon is now working through a version of this challenge. The Universal Health Plan Governance Board is tasked with delivering a comprehensive financing and administration plan to the legislature by September 15, 2026.

Oregon has advantages Vermont did not. It is larger, its economy is more diversified, and its political coalitions have had more experience defending public programs. None of that erases the underlying problem. A state still needs federal waivers and federal cooperation if it wants to consolidate funding that currently moves through Medicaid and other national programs.

Oregon’s process should take the Vermont record seriously without treating it as an instruction to give up. The state needs to resist two temptations.

The first is benefit austerity masquerading as realism. A universal plan cannot become meaningful by attaching the word “universal” to high cost-sharing and narrow access. If residents still avoid care because the out-of-pocket burden is too high, the system has reproduced the cruelty it claims to replace.

The second is fiscal mysticism. Savings from reduced administrative waste, more rational payment, and coordinated purchasing may be real. They are not a substitute for a revenue plan. Oregon will need to show what households and employers pay now, what they would pay under a public system, which federal dollars are dependable, and what happens if waivers or funding arrangements fall short.

The strongest application of Act 48’s lessons is not smaller ambition. It is sharper sequencing:

• Develop benefits and financing as one package rather than letting each evolve in isolation.
• Treat federal waivers as a political objective requiring organizing, not a technical box expected to be checked.
• Make premium replacement visible, especially for workers whose wages are already subsidizing employer healthcare costs.
• Protect low-income residents from a transition that simply converts private insecurity into a public tax burden.
• Build a coalition that includes patients, labor, providers, and small businesses without allowing any one bloc to quietly privatize the public interest.

Oregon’s 2026 roadmap will not settle the national debate. But it can clarify what responsible state-level planning looks like: ambitious about care, honest about revenue, and unsentimental about federal barriers.

The Fiscal Reality Is Political

When people ask how much universal healthcare will cost, the honest answer cannot be reduced to one number. It depends on the benefits, the payment rates, the revenue structure, the treatment of existing public funds, and whether the reform is enacted by a state or the federal government.

But the broader fiscal reality is already visible. The United States spends roughly 18% of GDP on healthcare—more than $4 trillion annually—while delivering poorer outcomes than many peer nations on life expectancy, maternal mortality, and preventable hospitalizations. The issue is not whether Americans pay enough. We pay too much, through too many channels, for a system that still permits illness to become debt.

The universal healthcare economic impact would not be confined to government budgets. It would reach wages, labor mobility, household debt, small-business costs, disability, public health, and the daily freedom to leave a bad job without losing access to a doctor. Those are not side effects. They are the point.

Vermont did not fail because its people wanted too much healthcare. It failed because a small state attempted to replace a national financing system without control over the national money. Green Mountain Care showed the limits of state power, the danger of vague savings promises, and the brutality of a political culture that recognizes the cost of taxes but not the cost of premiums.

The lesson is not retreat. It is scale.

Universal healthcare will ultimately require federal action capable of bringing Medicare, Medicaid, employer coverage, drug purchasing, and public revenue into the same democratic framework. Until then, states will keep testing the walls of a system built to protect insurers and employers from accountability.

The price is not the obstacle. The distribution of power is.
