i think the real problem is the legal system, malpractice insurance, and available technology. doctors have to buy malpractice insurance incase they screw up, because if they do then they can be sued for thousands or even millions of dollars. so they have to pay malpractice insurance which increases the overall cost of medical services.
the insurance then requires them to use more diagnostic technologies. more x-rays, more mri scans, more ulrasound scans, pet scans, cat scans, ekg, eeg, ect. firing up some of that equipment can cost thousands of dollars in materials, power, maintanence expendable components (xray film for example). malpractice insurance sometimes requires the doctors to perform more diagnostics than are neccisary. the doctor can no longer use gut instinct or skill. and must be certain what the problem is before they can perform any treatment.
you go to the emergency room with a broken arm, when back before doctors became money magnets, he would use his skills to locate the fracture is and set it in a cast, xray made things slightly better, but for somone with a low income it was considered optional. you do the same thing today, your arm will be in 4 different scanners before you even see a doctor, and your bill will be through the roof. then they tell you its just a sprang give you a sling and an overpriced bottle of asprin. it used to be you could go to a dentist to get a tooth pulled, now only an oral surgeon can do the task, and not without a bunch of xrays. were talking about a procedure you could get done at a barber shop for 5 bucks and a bottle of whisky a hundred years ago.
the insurance wont let them work without those scans as part of a legal agreement. i think that this level of certainty should be considered a luxury and not a requirement. the result of all of this is that medical bills are a lot higher than they need to be. average joes are being forced into paying a rich mans bill. some people just do without any health care at all because all they can get is top of the line care, which they cannot afford. the idea is that some care is better than none at all. dont even start with government funded health care till you can streamline the existing medical industry. only then would you be able to pull it off.
