Medicare (United States) - Wikipedia

Cutting costs by cutting benefits is difficult, but the program can also achieve substantial economies of scale in the prices it pays for health care and administrative expenses—and, as a result, private insurers' costs have grown almost 60% more than Medicare's since 1970.[citation needed][106][original research?][107] Medicare's cost growth is now the same as GDP growth and expected to stay well below private insurance's for the next decade.
