Note this chart, from Joshua Green's cover story on the fate of Simpson-Bowles and their efforts, including "Fix the Debt" shows that virtually all of the long-term spending issue is found in rising healthcare costs. So that might tell us that healthcare costs are a problem to be worked, by themselves.
And if seems to be the case that one good way to make healthcare cheaper is helping people to become healthier! A cure is cheaper than care.
Unfortunately, Simpson-Bowles had nothing to say about medical strategizing, other than cuts. The evidence seems pretty clear across the board: Any message on healthcare that's just cuts is not going to fly.
