Any bona fide universal health-care system must be single-payer by definition, lest the profit orientation of the insurance industry has free reign to deny coverage for anyone with pre-existing conditions or other arbitrary factors to preserve their bottom line for their shareholders. We do not have any "health" care system in the technical sense, as our present structure revolves around reactive approaches to ailments and diseases that have already occurred. Health care, as opposed to sickness care which is the nature of our profit-oriented approach, focuses on preventive medicine, which starts with a healthful vegan diet, ideally raw and organically grown as much as possible. Anyone eating the Standard American Diet based on flesh, dairy and eggs cannot ever hope to achieve optimal health or avoid becoming a drain on public health resources. Medical school rarely if ever teaches nutrition, so very few MD's have any integrity in promoting nutritionally adequate or life-promoting habits to their patients. Second to 100% vegan diet in priority is regular exercise as a daily routine. One's physical and mental muscles must be constantly exerted to prevent them from dying and disease. Furthermore, a true single-payer universal health-care system must include naturopathy, homeopathy, holistic massage therapy and other non-invasive forms of so-called "alternative" medicine to effectively treat patients in contrast to allopathy, which only treats symptoms as SOP.
