No country’s healthcare is truly free. Countries with universal systems pay for healthcare collectively, primarily through taxes or mandatory payroll contributions, so that nobody receives a bill at the point of care. The mechanics vary widely, but they share a core principle: spreading risk and cost across the entire population rather than linking coverage to individual ability to pay. Understanding how these systems actually work reveals why they consistently spend less than the United States while covering everyone.
Tax-Funded Systems: The Government Runs It
The most straightforward model is sometimes called the Beveridge Model, after the British economist who designed the UK’s National Health Service. In this approach, the government collects taxes, owns most hospitals, and employs (or contracts) the medical staff. The United Kingdom, Spain, New Zealand, and the Nordic countries all operate versions of this system. Citizens pay nothing or very little when they visit a doctor, get surgery, or stay in a hospital. The funding comes from general taxation, meaning everyone contributes proportionally through income taxes, sales taxes, or both.
Because a single entity controls both the funding and the delivery of care, these systems have strong leverage to control costs. The government sets hospital budgets, negotiates salaries, and decides how resources are allocated across regions. The tradeoff is that the government also decides priorities, which can mean longer waits for non-urgent procedures.
Social Insurance: Employers and Workers Split the Bill
Germany, France, Japan, and Switzerland use a different approach rooted in mandatory insurance. Workers and employers each pay into nonprofit insurance funds through payroll deductions, similar to how Social Security works in the U.S. These funds then pay private doctors and hospitals for care. Germany has operated this way for over 135 years.
The critical difference from American private insurance is that these insurers are tightly regulated and typically nonprofit. They cannot deny coverage for preexisting conditions, and the government sets or negotiates the prices that providers can charge. People don’t choose whether to have insurance. It’s automatic, funded through their paycheck, and covers a comprehensive set of services. Wealthier citizens in some of these countries can opt into private insurance for extras like private hospital rooms or shorter waits, but the baseline coverage applies to everyone.
Government Payer, Private Doctors: The Canadian Approach
Canada blends elements of both models. Most physicians are self-employed in private practices, and hospitals are a mix of public and private nonprofit organizations. But the bills go to provincial governments, not to patients. Each province negotiates a fee schedule with its medical associations, and doctors bill the government directly at those rates. Physicians are not allowed to charge patients above the negotiated fee schedule.
Hospitals operate under annual global budgets negotiated with provincial health ministries. Doctors working inside hospitals generally aren’t hospital employees. They’re independent practitioners paid fee-for-service by the province. This setup preserves the private practice of medicine while eliminating the need for patients to navigate insurance companies, file claims, or worry about network restrictions. South Korea and Taiwan run similar systems.
One important restriction: specialists who bill the public insurance plan cannot simultaneously accept payment from private insurers for services the public plan would cover. This prevents a two-tier system where wealthy patients could buy faster access to the same publicly funded doctors.
How These Systems Keep Costs Down
Universal systems use several strategies that the U.S. largely does not. The most impactful is centralized price negotiation. When a single payer (or a small number of regulated payers) represents an entire country’s population, it has enormous bargaining power over drug companies, device manufacturers, and providers. For context, the U.S. Veterans Administration healthcare program, which does negotiate drug prices directly, pays on average 54% less than the Medicare Part D program for the same medications.
Administrative savings are equally significant. The U.S. spent $925 per person on health administration in 2021, compared to $245 per person on average in comparable countries. That $680 gap per person exists because multi-payer systems require enormous bureaucracies on both sides: insurers employ staff to process claims, deny claims, and manage networks, while hospitals and doctors employ staff to bill dozens of different insurers, each with different rules. Administrative costs eat up about 7.6% of total U.S. health spending versus 3.8% in comparable countries. These figures don’t even include the administrative burden inside doctor’s offices and hospitals, only insurer and government overhead.
Other countries also set standardized prices for procedures, which eliminates the wild price variation seen in the U.S., where the same MRI can cost $500 at one facility and $3,000 at another across town.
What They Spend Versus What the U.S. Spends
The spending gap is dramatic. In 2024, OECD countries allocated about 9.3% of GDP to health on average. The United States spent 17.2% of its GDP on healthcare, nearly double the average and far above Germany, the next highest spender at 12.3%. A group of about 15 countries with well-regarded universal systems (including France, Canada, Australia, and Japan) all fell in the 10 to 12% range. The U.S. has consistently outspent every other OECD country, exceeding 17% of GDP throughout recent years and peaking at 18.5% during the pandemic in 2020.
This means the U.S. spends roughly twice as large a share of its economy on healthcare as most countries with universal coverage, while still leaving tens of millions uninsured or underinsured.
The Real Tradeoff: Wait Times
The most common criticism of universal systems is waiting. And it’s a legitimate concern, particularly for elective procedures. For hip replacement surgery in 2024, median wait times ranged from 67 days in Sweden and Spain to over half a year in Hungary (209 days) and nearly two years in Slovenia (667 days). Following large increases during the pandemic, most countries have seen wait times return toward pre-pandemic levels, though some like New Zealand and Slovenia have continued to get worse.
These waits generally apply to non-emergency, elective procedures. Emergency and urgent care is triaged the same way it is everywhere: the sickest patients go first. And some universal systems manage wait times quite well. Poland, for instance, saw large reductions in surgical wait times after increasing funding specifically for common procedures like cataract, hip, and knee replacement surgeries starting in 2019. This illustrates an important point: wait times in universal systems are often a political choice about funding levels, not an inherent flaw of the model.
What “Free” Doesn’t Cover
Even in countries with universal healthcare, “free” rarely means every medical service is included. Most universal systems exclude or only partially cover dental care, vision care (especially eyeglasses and contact lenses), cosmetic procedures, and certain prescription medications. Citizens typically pay for these through supplemental private insurance, employer benefits, or out of pocket.
In Canada, for example, prescription drugs outside of a hospital setting are not universally covered by the public system, though provinces run their own drug benefit programs for seniors, low-income residents, and others. Many Canadians carry private insurance through their employers specifically for prescriptions, dental, and vision. The UK’s NHS covers prescriptions but charges a flat dispensing fee per item in England (Scotland, Wales, and Northern Ireland have abolished this fee). Mental health services, physiotherapy, and fertility treatments also vary widely in coverage from country to country.
These gaps mean that even in universal systems, people with more money generally get more comprehensive care. The difference is that the baseline, which includes doctor visits, hospital stays, surgery, emergency care, maternity care, and cancer treatment, is available to everyone regardless of income or employment status.
Why It Works: Risk Pooling at Scale
The fundamental mechanism behind all these models is the same one behind any insurance system, just applied to an entire population without exceptions. When everyone is in the pool, healthy young people subsidize sick older people, wealthy taxpayers subsidize lower-income families, and the administrative machinery of determining who qualifies, who’s in-network, and who owes what largely disappears. The result is a system that covers more people, produces comparable or better population health outcomes, and costs significantly less per person.
The OECD average for maternal mortality, one common benchmark of healthcare system performance, was 10.3 deaths per 100,000 live births in 2023. The U.S. consistently reports rates several times higher than peer nations with universal systems, despite spending far more. Spending more doesn’t automatically translate to better outcomes when a significant share of that spending goes to administration, price inefficiency, and care for conditions that worsened because people delayed treatment they couldn’t afford.
