Much like every other aspect of the U.S. ponzi economy, the healthcare system is one gigantic centralized oligopolistic racket. The New York Times has done some excellent coverage on this topic as of late, most recently in an article I highlighted earlier this month about how Americans are now finding themselves forced to travel overseas for surgery.
That article demonstrated how the medical industry is simply one huge convoluted racket, in which contracts are secret and no one has any clue about anything except for a small group of players involved. In fact, it reminds me of an incredible article from 1982 that explains how diamonds are actually basically worthless, and that the whole market is a gigantic con. You take something that is essentially free, and then charge a fortune for it through middleman markups.
