Single-payer national health insurance is a health care system is which a single public agency organizes health care financing, but the delivery of health care would remain in private hands. Currently, the US spends $10,348 per person, which is by far the most in the world (second is Switzerland with $7,919 person.) However, the US has by no means the best health care in the would. The WHO ranks the US as the 37th best healthcare system in the world, and millions of Americans are still uninsured. Single payer countires rank highly on the list, and bringing single payer to the US would help push the number of uninsured Americans to zero. Bernie Sanders intoduced his "Medicare For All" bill to the Senate Finance Committee last year, and current bipartisan calculations estimate this healthcare system to cost the goverment $32 trillion over 10 years. https://www.mercatus.org/publications/federal-fiscal-policy/costs-national-single-payer-healthcare-system and https://www.urban.org/urban-wire/what-would-it-take-make-single-payer-health-care-reality Currently, 49% of Americans support single payer, and its popularity is rising. Could single-payer be implemented in the US, or is it too much of a challenge? Also, what systems could work better or be more feasible in the US?
