> Every other nation on earth somehow finds a way to deal with that.

well not every other nation, but i know what you mean.

other nations are much better at managing overutilization by denying care where it is not needed. the US insurance system shields people from cost and encourages overutilization due to a number of stupid policy choices (aka refusal to have 'death panels' like in Canada/UK but also refusal to do away with massive publicly subsidy for health expenditure).

for a personal story, my parents basically get free MRIs from the state for little reason whereas people I know have to pay an arm and a leg for MRIs because their insurance is worse. at minimum, we could at least also make my parents have to pay an arm and leg for useless MRIs and doctors would stop encouraging them or lose patients.
