I thought this article laid out the real problem with Medicare, and the entire health care system; it's the overall cost of care in the first place.
The GOP's solution to fixing our health care system is to repeal “Obamacare” and cost-shift the Medicare problem on to the backs of future Medicare recipients. Fixing a fiscal problem should not rely on simply cost-shifting the problem to a subset of the population (e.g. Medicare recipients) or the entire population. Solving that problem should involve removing the underlying causes so that the problem doesn't become some endemic part of our culture.
