I suppose this poll first appears more disheartening than it may be, because (upon my viewing) roughly 62% of the 232 voters believe that healthcare is more likely to be disrupted than not. However, I'm surprised that employers are ranked at the bottom, since they experience both a magnitude and directness of pain due to rising costs that isn't necessarily perceived by even some patients.
None of the above because the health care system in this country is too imbedded in politics and special interests. I would have said 'Government' but after thinking about it no politician wants to upset a major 'entitlement' program. Social Security and Medicare remember are referred to as the third rail of politics.
How about researchers? People who are paid to study the problems, come up with new ideas, and design new solutions are the most likely to ultimately benefit patients in my humble opinion.
