Great Series of Post Explaining Why US HC Costs Are So High

I think this is a must read given the first three blogs in this series that I have read. (http://theincidentaleconomist.com/wordpress/what-makes-the-us-health-care-system-so-expensive-introduction/) The posts are to the point and well illustrated with charts and graphs. So far the author, Aaron Carroll, has covered inpatient care, outpatient care and drug costs with more posts to come. Really good stuff.
