A single-payer government healthcare system is an example of a buyer's monopoly. Under such a system, the government would be the only buyer of health services. This would give the government considerable power over health care providers. It is sometimes argued that such a system would be advantageous to citizens because a government-controlled buyer's monopoly could gain sufficient market power to drive down the prices charged for healthcare services. Critics claim that a dead weight loss would occur if the quality or availability of health care declined due to the enactment of such a system.
