The future economic need of the US health care system is for some sort of mechanism by which the rising cost of care can be controlled.
Of course, the health care industry would prefer that costs be allowed to rise. This would allow them to make more money. But this would not be good for the industry in the long run. The cost of health care in the US is rising at an untenable rate. There is already a major crisis in Medicare, which pays for the care of elderly Americans. If costs continue to rise, the economy as a whole could be gravely damaged, thus harming the health care industry as well.
Therefore, there is a need for something that will lower costs. The current system rewards providers for giving more quantity of care, regardless of the cost. This is not workable in the long term. The cure for this is not clear. There are major disagreements between the political parties as to how this could be accomplished. But one way or another, lower costs are the greatest future need of the health care system.
