“Medicare for all,” or “single-payer,” is becoming a rallying cry for Democrats.
This is often accompanied by calls to match the health care coverage of “the rest of the world.” But this overlooks a crucial fact: The “rest of the world” is not all alike.
The commonality is universal coverage, but wealthy nations have taken varying approaches to it, some relying heavily on the government (as with single-payer); some relying more on private insurers; others in between.
Experts don’t agree on which is best; a lot depends on perspective. But we thought it would be fun to stage a small tournament.
We selected eight countries, representing a range of health care systems, and established a bracket by randomly assigning seeds.
- Aaron Carroll, a health services researcher and professor of pediatrics at Indiana University School of Medicine
- Austin Frakt, director of the Partnered Evidence-Based Policy Resource Center at the V.A. Boston Healthcare System; associate professor with Boston University’s School of Public Health; and adjunct associate professor with the Harvard T.H. Chan School of Public Health
and three economists and physician experts in health care systems:
- Craig Garthwaite, a health economist with Northwestern University’s Kellogg School of Management
- Uwe Reinhardt, a health economist with Princeton University’s Woodrow Wilson School of Public and International Affairs
- Ashish Jha, a physician with the Harvard T.H. Chan School of Public Health and the director of the Harvard Global Health Institute
A summary of our worldviews on health care is at bottom.
So that you can play along at home and make your own picks, we’ll describe each system along with our choices (the experts’ selections will decide who advances). When we cite hard data, they come from the Commonwealth Fund’s International Country Comparison in 2017.
But enough talk. Let’s play.
