You seem to have difficulty with reading comprehension since I have explicitly written several times in this thread that (a) I support single payer and even nationalized health care in this country, and (b) that universal high quality coverage is an important determinant of health.
That is a separate claim from what is needed to get the US’s population health measures (life expectancy, infant mortality, etc.) from just below Cuba’s to up near Finland’s or Japan’s (i…e addressing the major determinants of illness and health).
