Medicare spending

I worked in the health insurance industry for a long time.  I helped introduce consumer-driven/high deductible plans to help foster cost-awareness.  I bought into the protection-against-big-expenses meme.  I personally have never not had health insurance.  So, by most standards, I should be biased in its favor.  But I'm beginning to wonder if health insurance itself is the problem, or at least a big part of the problem. I've written before about some of the new entrants into health insurance; more power to them, and the more the merrier.  What I continue to be disappointed by is that we're not really seeing fundamentally new approaches to what health insurance is.
