John Green of VlogBrothers talks about why American healthcare costs are so high. It’s really fast and well done and features facts and graphs. The articles and posts he links to are worthwhile reads as well.
By the way, John Green is also the author of The Fault in Our Stars, which is a pretty damn good book which I would recommend to pretty much everybody. Maybe not the people who don’t read, or don’t like fiction, but everyone else, including those of you who read less than five books a year. :)
