Goldfish? But wouldn't they be protein???
Hospitals are not doing well financially. They are very expensive to run and maintain. The charges are mostly written off for people who have insurance and/or Medicare. Medicare, by the way, pays according to diagnosis. If you have a suspected heart attack and are in the hospital overnight, Medicare will mostly pay the same amount, no matter how many tests you have. I'm not sure if private insurance has gone there in general or not, but the private insurers do tend to follow Medicare's lead...
