I find that explaining the “socialized” medical systems to Americans can best be done by analogy to the police department.
The police provide services to everyone, paid for by everyone (through taxes.) They set up a priority system – which cases are more urgent. For instance, when my 70-year old neighbor recently called the police because a bird flew down her chimney, she was told that they would get there eventually, but it was obviously a fairly low priority. She accepted that. If she had wanted faster action (or if I didn’t want to use the police but wanted a private cop), she could have paid for one.
Social medicine is much the same. The services are available to everyone, paid for by everyone (through taxes.) They have a priority system, which means that some cases will have long waits. If you want to bypass the queue, and you can afford it, you can always buy private.
No medical system is perfect, not until we can find a way to provide immediate, high-quality care to everyone at no cost. Every system will have its share of problems – Lord knows, the American free-enterprise medical system is not without flaws. Medical care is a limited resource. Under a social system, the allocation of that resource is based on need, as defined by the community (or by medical boards representing the community.) Under the U.S. system, the allocation of that resource is based on financial ability to pay.
Yes, there may be long waits under a social system. In contrast, there are people in the U.S. who never even seek treatment, because they can’t afford it. Our former cleaning woman always waited until her son was sick enough to warrant a visit to the emergency room (which was paid by Medicaid), rather than seek earlier treatment from a doctor (which she would have had to pay for.) So, there are still “long waits” under the U.S. system – you just never see them, and they’re not recorded statistically.
