As the nation gears up for the 2020 election, Democrats are promising bold new changes to the American health care system. One idea championed by many on the progressive left is “Medicare for All,” or a single-payer system, which would do away with private health insurance for most forms of care. Advocates of this plan promise that nationalizing health insurance will cut costs by reducing overhead and promote overall health by giving all Americans access to preventive health care. And in doing so, the United States will join the ranks of many other developed nations that have already mandated a national insurance program to guarantee medical care as a basic human right. Their opponents argue Medicare for All is a political non-starter that would force Americans off employer-based plans, reduce incentives for doctors and providers, increase bureaucracy and inefficiencies in the system, and lead to worse care overall, all the while inflating the already swelled federal deficit. Should private health insurance exist? Or is it time for Medicare for All?
