 Some in the U.S. argue that if government were to use its size to bargain down health care prices, this would undermine American leadership in medical innovation.It is argued that the high level of spending in the U.S. health care system and its tolerance of waste is actually beneficial because it underpins American leadership in medical innovation, which is crucial not just for Americans, but for the entire world.Others point out that the American health care system spends more on state-of-the-art treatment for people who have good insurance, and spending is reduced on those lacking it and question the costs and benefits of some medical innovations, noting, for example, that "rising spending on new medical technologies designed to address heart disease has not meant that more patients have survived."
