what is the idea behind a single payer system of health insurance
Single-payer healthcare Single-payer healthcare is a healthcare system financed by taxes that covers the costs of essential healthcare for all residents, with costs covered by a single public system (hence 'single-payer').[1][2] Alternatively, a multi-payer healthcare system is one in which private, qualified individuals or their employers pay for health insurance with various limits on healthcare coverage via multiple private or public sources.[3][4]
