Healthcare isn’t free in the United States because the country built its system around private insurance, employer-sponsored coverage, and market-based pricing rather than a government-funded model. This wasn’t inevitable. It was the result of specific political decisions made over decades, economic interests that grew powerful enough to resist change, and a tax structure that locked employer-based insurance into place before a public alternative could gain traction. The U.S. now spends 17.8% of its GDP on healthcare, nearly twice the average of comparable countries, yet has the lowest life expectancy among high-income nations.
How Insurance Got Tied to Your Job
The roots of the current system trace back to World War II. During the 1940s, the federal government froze wages to control wartime inflation, which meant employers couldn’t compete for scarce workers by offering higher pay. What they could do was offer health insurance as a benefit. The government indirectly encouraged this by making employer contributions to health insurance tax-free, which made it far cheaper for companies to provide coverage than to raise salaries by the same amount.
This was supposed to be a wartime workaround. Instead, it became permanent. When the Eisenhower administration took office, the IRS considered taxing employer health benefits. Eisenhower pushed Congress in the opposite direction, and Congress agreed: employer contributions to health insurance would remain tax-free. That single decision cemented the employer-based model as the backbone of American health coverage. Once millions of workers had insurance through their jobs, the political appetite for a government-run alternative shrank dramatically. Every subsequent attempt to create a universal public system has had to contend with an entrenched industry of private insurers, hospital networks, and pharmaceutical companies that grew up around this structure.
Where the Money Actually Goes
The U.S. doesn’t lack healthcare spending. It has more of it than any other country on Earth. In 2024, private health insurance accounted for 31% of total national health expenditures, or about $1.6 trillion. Medicare (the federal program for people 65 and older) made up 21%, and Medicaid (coverage for lower-income Americans) accounted for 18%. Out-of-pocket costs from patients themselves represented another 11%, totaling roughly $557 billion.
So the government already funds a massive share of healthcare. The difference is that this funding is fragmented across multiple programs, each with its own eligibility rules, payment structures, and administrative overhead. That fragmentation is expensive. Administrative costs eat up about 7.6% of total health spending in the U.S., compared to 3.8% on average in comparable countries. Every private insurer negotiates its own rates with every hospital and doctor. Every hospital employs billing staff to navigate dozens of different insurance plans. Every doctor’s office spends hours on prior authorizations and claims. In a single-payer system, much of that paperwork disappears because there’s one payer with one set of rules.
Why Everything Costs More Here
The price of medical care in the U.S. is dramatically higher than in peer nations, and this is one of the biggest reasons the system costs so much. U.S. manufacturer prices for prescription drugs in 2022 were 278% of prices in 33 other OECD countries. For brand-name drugs specifically, the gap was even wider: American prices were 422% of what other countries paid. Even after accounting for rebates that drug companies pay back to insurers and pharmacy benefit managers, brand-name drug prices in the U.S. remained 308% of international prices.
Generics tell a different story. Unbranded generic drugs in the U.S. actually cost about 67% of what they cost abroad, and generics make up 90% of prescriptions filled in the country. But brand-name drugs account for a disproportionate share of total spending because they’re so much more expensive per prescription. A single brand-name specialty medication can cost more per month than a year’s worth of generics.
Most countries with universal healthcare use their purchasing power to negotiate drug prices directly. Because the U.S. system has many separate buyers (private insurers, Medicare, Medicaid, the VA), no single entity has historically had the leverage to drive prices down the way a national health service can. Hospital and physician prices follow a similar pattern. Inpatient and outpatient care represent about 62% of total health spending in the U.S., compared to 46% in comparable countries.
What You Do Get for Free (and Its Limits)
The U.S. does guarantee one narrow slice of free care. Under the Emergency Medical Treatment and Labor Act, passed in 1986, any hospital that participates in Medicare (which is nearly all of them) must screen and stabilize anyone who shows up to the emergency room, regardless of their ability to pay. If you’re in active labor or having a heart attack, the hospital cannot turn you away or demand payment first.
But EMTALA only covers emergency stabilization. Once you’re stable, the hospital has no obligation to continue treating you for free. You will still receive a bill. And the law doesn’t cover routine care, chronic disease management, preventive screenings, or prescriptions. Relying on emergency rooms as a safety net is also wildly inefficient: ER visits cost far more than the same care delivered in a primary care office, and by the time someone shows up in an emergency, their condition is often far more advanced and expensive to treat than it would have been with earlier intervention.
Nonprofit hospitals have additional obligations. To maintain their tax-exempt status, the IRS requires them to establish a written financial assistance policy that covers emergency and medically necessary care. These policies must specify who qualifies for free or discounted care, be widely publicized, and ensure that eligible patients aren’t charged more than what insured patients typically pay. In practice, many patients who qualify for charity care never learn about it, and hospitals vary enormously in how generous or accessible their programs are.
Spending More, Getting Less
The cost of this system would be easier to justify if it produced better health. It doesn’t. The U.S. had a life expectancy of 77 years in 2020, three years below the OECD average. Germany spends less per person on healthcare than the U.S. and has a life expectancy nearly four years higher. The U.S. infant mortality rate in 2020 was 5.4 deaths per 1,000 live births, the highest of any high-income country analyzed by the Commonwealth Fund. The U.S. also has the highest rate of avoidable deaths among these nations.
Health spending per person in the U.S. is nearly double that of Germany, the next-closest country, and four times higher than South Korea’s. These gaps aren’t explained by Americans using more healthcare. They’re driven by higher prices, higher administrative costs, and a system where tens of millions of people delay or skip care because they can’t afford it, then end up needing more expensive treatment later.
Why It Hasn’t Changed
Multiple presidents have tried to create a universal system. Harry Truman proposed national health insurance in 1945 and was blocked by opposition from the American Medical Association and accusations of socialism. Lyndon Johnson succeeded in creating Medicare and Medicaid in 1965, but only for the elderly and the poor. Bill Clinton’s universal coverage plan failed in 1994. The Affordable Care Act in 2010 expanded coverage to millions but preserved the private insurance framework.
The obstacles are partly ideological. A significant portion of American political culture views government-run programs with skepticism and prioritizes individual choice and free-market competition. But the obstacles are also structural. The health insurance industry, pharmaceutical companies, and hospital systems spend billions on lobbying. Employer-sponsored insurance, despite its inefficiencies, works well enough for the majority of working Americans that there’s limited political pressure for radical change. And the tax exclusion for employer health benefits costs the federal government hundreds of billions in foregone revenue each year, effectively subsidizing the private system in a way that’s invisible to most people who benefit from it.
What a Single-Payer Switch Would Look Like
The Congressional Budget Office has modeled what would happen if the U.S. transitioned to a single-payer system. The results depend heavily on the details. Without accounting for how the system would be financed, economic output after 10 years could range from 0.3% lower to 1.8% higher than the current trajectory. Average private spending on non-health goods and services (basically, what people have left over after healthcare costs) could rise by about 11.5% by 2030, because households would no longer pay premiums or most out-of-pocket costs.
The harder question is how to pay for it through taxes. If funded by income or payroll taxes, GDP could fall by 1% to 10% by 2030, depending on the generosity of the plan and the tax rate required. Non-health consumption per person could range from 3% higher to 7% lower. The wide range reflects genuine uncertainty: a lean single-payer plan with cost controls could save money overall, while a generous plan with no cost-sharing could be significantly more expensive. One consistent finding across models is that people would choose to work slightly fewer hours, because they’d no longer need a full-time job just to maintain health coverage.
The U.S. system isn’t the result of a single decision or a single villain. It’s the accumulated weight of 80 years of policy choices, economic incentives, and political compromises that created an industry too large and too entrenched to easily replace. Other countries made different choices at key moments and built systems where the government negotiates prices, covers everyone, and spends less doing it. The U.S. locked in a different path, and reversing course would require not just political will but a fundamental restructuring of an industry that accounts for nearly a fifth of the entire economy.
