Normally, my writing focuses on technological and structural innovation in health care — factors that can bring better health to more people at lower cost. But with the 2018 and 2020 elections approaching, single-payer health insurance is back on America’s front burner — especially the “Medicare for All” (M4A) bill proposed by Senator Bernie Sanders of Vermont.
