Democratic presidential candidates Elizabeth Warren and Bernie Sanders have struggled to explain how they would pay for “Medicare for all.”

This is puzzling. A single-payer approach like Medicare for all can reduce overall health spending. Other wealthy countries that have universal coverage spend far less on healthcare than the United States as a share of their gross domestic product. A lack of money is not the problem. That’s why it should not be difficult to devise a way to pay for Medicare for all to benefit the vast majority of us, particularly low- and middle-income earners.

In fact, Canada has such a system, which should cast doubt on all the naysayers who claim that it is impossible or ruinous. Canada, with a single-payer system, spends half of what we do on healthcare and gets better results. Britain, France, Australia and Japan, all with universal healthcare, also spend less than half of what we spend per capita and get better results.

Medicare for all is widely expected to cost about $3 trillion a year. The government — through Medicare, Medicaid, CHIP, and various other programs — already pays more than $1.5 trillion of this healthcare bill. Private insurance and out-of-pocket costs account for another roughly $1.5 trillion. Going to Medicare for all would increase the budget of the government by about $1.5 trillion a year.


Here are some ideas on how to fund it:

End the cap on payroll taxes and apply payroll taxes to all income, including interest and capital gains. This will not have a significant effect on anyone whose income is less than $132,900, the current cap, and will raise about $1.5 trillion. Those making somewhat above the current cap will end up paying a bit more, but they will not have to pay health insurance premiums or out-of-pocket medical expenses and will come out ahead.

Large employers now pay on average $6,000 per employee for individual health insurance and $14,000 per employee for family health insurance. Many smaller employers pay similar rates, as do the self-employed. Let’s suppose that we tax all employers $5,000 per year per employee and relieve them of the burden of providing employee insurance. Most come out way ahead. This raises about $650 billion.

Elizabeth Warren’s proposal of a 2% wealth tax on wealth over $50 million would raise another $250 billion a year. Her proposed corporate tax on off-shore earnings would raise $100 billion a year by requiring companies like Amazon to pay taxes on their worldwide income.


Finally, if Canada, spending less than half of U.S. expenditures on healthcare, has better health outcomes, that suggests there are savings to be had. Let’s be conservative. Suppose a Medicare for all system can help the U.S. cut total health spending by 20%. That would save us $600 billion — and still leave us with the highest per person healthcare spending in the world.

If we add all of these together, that would be more than $3 trillion in additional revenues or savings per year, well over the $1.5 trillion in additional government spending necessary to fund Medicare for all.

None of this would increase the burden on the middle class or the poor. Indeed, without insurance premiums and out-of-pocket expenses, their overall costs would fall dramatically. And none of this puts an excessive burden on the rich. Corporations would reap huge savings. And all Americans would get healthcare, with enough left to invest in other health, wellness and education programs.

These are just a few ideas, and others may be even more attractive. These simply demonstrate that we can have Medicare for all without ruining the economy or raising taxes on middle- and low-income earners. Let’s do it.
