This is something I don't get an explanation for anywhere. It's crazy that ordinary people can't afford quality care. The problem is that the price of delivering health care in America bears zero relationship to its cost.
A friend of mine had knee surgery. The sticker price was $165k. But thanks to "negotiated rates", his insurance was billed only $15k, and his co-pay was 20%, or 3000 bucks. The three grand might actually be the true cost of performing the operation: an hour or so of a surgeon, anesthesiologist, some pre-op, op, and post-op nursing, plus assorted bits and bobs like suture and bandages and sterilizing hemostats, etc.
