Sen. Bernie Sanders’ once-quixotic campaign to abolish private health insurance in the U.S. — most of it employer-sponsored — in the name of “Medicare for all” has now become the leading progressive litmus test for anyone seeking the Democratic Party’s presidential nomination. Twelve of the remaining candidates subscribe to it, in various versions.

Unfortunately, the progressives’ eagerness to upend the entire $3.5 trillion U.S. health care system while canceling the current health insurance of 217 million Americans is based on some serious misconceptions.

It disregards what other countries actually do to achieve near-universal access to health care; it underestimates the financial consequences for Americans; and it fails to recognize how much easier it would be to achieve the same — or better — health care outcomes by building on, rather than dismantling, the Affordable Care Act.

While Sanders is correct that most advanced countries guarantee health care to nearly all their residents, they do not necessarily do this through a single-payer national program like Medicare.

Most notably, some of the richest European countries like the Netherlands, Switzerland and Germany have what might be called “Health for all,” the central feature of the Affordable Care Act.

Canada has what might be called Medicaid for all, provincial programs that vary in benefits offered.

England has the equivalent of the U.S. Veterans Affairs health care program “for all,” with hospitals and health care providers directly supported by the national government.

Every country so admired by the Democratic progressives guaranteeing universal access to health care also has a large role for private insurance.

Even Sanders acknowledges that the cost of Medicare for all will be staggering. The Urban Institute, a policy research organization, estimates that the approach would add $2.54 trillion annually to the federal budget. Even if that were entirely offset by eliminating expenditures on private insurance (currently $1.68 trillion), that leaves $860 billion per year to be shouldered by federal taxpayers.

What is most surprising about the Democrats’ advocacy of Medicare for all is their rejection of the Affordable Care Act as a more realistic foundation for universal access to health care.

Not only does the ACA incorporate elements of other countries’ approaches to universal health care coverage, it has provided health insurance to 20 million more Americans, cutting the uninsured rate by over 40%, according to Kaiser Family Foundation.

The ACA has also protected millions with preexisting health conditions from losing coverage, enabled young adults to be covered by their parents’ insurance, and made the scope of benefits more comprehensive and consistent for most Americans. And it has enabled states to test ways to use their Medicaid grant allocations to deliver more effective health care.

Unless it is overturned by a pending court challenge, the ACA is still the law, and can be strengthened to close the coverage gap both by executive order (undoing recent actions to weaken it) and a few reasonable amendments.

First, restore the requirement that all Americans have health insurance and reinstate the subsidies that enabled uninsured middle-income individuals to afford private insurance offered on federal and state online insurance exchanges. More than 14 million more Americans can gain coverage this way, and it would have the additional benefit of lowering the cost of insurance premiums for everyone.

Second, improve incentives to get the 14 states that declined to join the Medicaid expansion program to opt in. This would immediately insure an additional 2.5 million Americans. Finally, to get to universal coverage, make a low-cost public health insurance option available for the 10 million Americans who can’t afford even subsidized private policies, but have incomes too high to qualify for Medicaid.

These fixes together would cost an estimated $200 billion annually, much of it in foregone taxes.

All Americans deserve access to health care equal or superior to that of other advanced nations. However, this does not require massively disrupting an industry that accounts for one-fifth of the U.S. economy, or legislation that has no realistic chance of passage, or a wildly extravagant increase in the federal budget. The ACA has already moved the U.S. a long way toward universal access. Building on it with feasible reforms can finish the job.
