One of the criticisms of the “Medicare for All” government-run health care scheme proposed by U.S. Democratic presidential candidates Bernie Sanders and Elizabeth Warren is that eliminating all limits to treatment would lead to "overuse" of the medical care system, meaning people would be seeing doctors for every little perceived ailment, which is wasteful. Given the vast number of Americans who presently forego medical attention because they cannot afford private insurance, overuse of medical resources should be considered at worst a necessary evil.
