First of all, I should thank all of you. Our income comes entirely from the Indian Health Service, so your taxes paid for this computer, and everything else in our house!
There needs to be some level at which health care is not a "for-profit" private enterprise. We have lived on two reservations, and before that, in a very rural, remote area. Take our present circumstance, as an example. The nearest decent-sized town is two hours from here, Port Angeles. We live in a very small fishing village. As with most reservations and extreme rural settings, the population is mostly quite poor. Unemployment is high. These are people without a lot of wealth. Without an IHS-run clinic here, what would be the incentive to have a health care facility here at all? It's doubtful that it would be profitable, in fact I am sure it would not be. So our entire population would be two hours from the nearest hospital. That's OK for primary care, perhaps, but what about an emergency? Even with the small clinic that IS here, my wife has to send people out by helicopter to Seattle on a regular basis.
Private practices tend to gravitate to where the money is. So if private practice is all there was, who in their right mind would set up a health clinic in a place where they know most people cannot pay them? The idea of universal health care is to me not an issue of "dumbing down" health care. Those who can afford to go to "Dr. Fancypants Clinic" should be allowed to. Universal health care is about access, not for those who have it already, but for those who have little or no access.
The other problem with "pay as you go" for everyone, is that it hurts the poor. People with less money are likely to pass up important treatments if they feel they cannot afford them. A doc might say, "you really ought to get an angiogram, it costs $150." Well, the guy just shelled out $75 for the visit, he might decide that financially he's just going to have to take the risk of NOT getting the angiogram. Patients would be making sometimes vital (and uneducated) choices about their health care based solely on their current financial situation. Even those of us with plenty of money would be encouraged by such a system to question treatments. Not that we shouldn't question our doctors, we should. But are we going to agree to what MIGHT be vital testing when we're not SURE of a pathology?
There's a huge grey area in medical science. If your arm is broken, you take steps A, B, and C and it's fixed. But what about more nebulous, unspecified problems? With insurance, a health care provider can say, "this could be a precursor to heart disease, I want you to get X and Y tests done." The context of possible heart disease would enable insurance to (probably and hopefully) cover the testing. Eliminate that, and you have people making uninformed choices that roll back the ideas of preventive care by decades. There are a lot of areas in medicine where the pathology is not obvious.
Universal health care would lower the cost, because uninsured people would not have to resort to ERs as a primary care facility, or wait until they practically fall apart to seek medical attention, again from an ER. If primary and preventive care were universal, there would be fewer people needing to be treated for preventable diseases and conditions, and the cost of health care would come down.
Please excuse my long rant!
