Yes, it is complicated, and expensive, and problem of access and quality, and more, much more.
I have been in health care, financing health care and managing delivery systems for over thirty years. Much has change, sorta, but much has not and that is one of the major problems facing the entire issue of what we can change and what we can do to do more with less. Because less is what we have.
One of the most prized and support qualities of our health care system, that in the US, is choice. Choice we might have, but choice as to outcomes and how well we live and function is not necessarily a part of what we have.
If it is numbers of providers, we have it, if it is what is the best for one and all, or someone in particular, we don't, and probably won't for a long time. What we do have is the choice to spend more and get less, and at a sacrifice to those who need the service and those who pay for what is done.
Much of what has been debated of late is the cost, not much has been debated as to what is done and as to what result.
We are not a healthy country. We are not a healthy people and we have probably done the most to make it that way ourselves. The question is what do we do about the issue of what we are receiving and what we get for our investment, mostly of the investment of our children's future income, and of the most productive people and industries we can tax.
