This study by PERI researchers Robert Pollin, James Heintz, Peter Arno, Jeannette Wicks-Lim and Michael Ash presents a comprehensive analysis of the prospects for a Medicare for All health care system in the United States. The most fundamental goals of Medicare for All are to significantly improve health care outcomes for everyone living in the United States while also establishing effective cost controls throughout the health care system. These two purposes are both achievable. As of 2017, the U.S. was spending about $3.24 trillion on personal health care—about 17 percent of total U.S. GDP. Meanwhile, 9 percent of U.S. residents have no insurance and 26 percent are underinsured—they are unable to access needed care because of prohibitively high costs. Other high-income countries spend an average of about 40 percent less per person and produce better health outcomes. Medicare for All could reduce total health care spending in the U.S. by nearly 10 percent, to $2.93 trillion, while creating stable access to good care for all U.S. residents.
