I'm guessing that you are fairly young. Am I right? I'm impressed with your thinking in any case. And not because I agree with you, but because it's logical!
There are two major problems the U.S. faces today. They are out of control health care costs, and out of control military spending. Incorrectly one hears politicians, and the media harp on "entitlements" as if all entitlements were a major part of the problem. This is dead wrong. Only one entitlement is significant here, medicare/medicaid, and the problem has nothing whatsoever to do with the fact that it is an "entitlement"! So a very big reason we can't make progress is the false and misleading rhetoric. There is both an ideological and financial force bolstering this false rhetoric, and that's going to make it virtually impossible to get it right!
If the U.S. could fix these two impossible to fix problems --medical and military--it could return to a robust and healthy economy with a large middle class, as it once had. But I doubt these these things will be properly fixed in my lifetime, because to do so would require logic trumping human nature.
We can summarize human nature very nicely as Malcolm Muggeridge did, by recognizing that all human activities are driven by some combination of vanity, greed, and instinct. These always trump logic, except in the rare, serendipitous occasion when you make more money, I make more money, and by pure chance, it's logical. In the case of medical and military I don't see any way around the problem in an atmosphere of false rhetoric. Perhaps I'm wrong and a brilliant solution can be found that allows a combination of logic, vanity and instinct to trump greed -- but it is usually the other way round.
Here, I only want to briefly discuss the medical problem.
I am old! I was raised in a family of physicians, grandfather (19th and 20th centuries), father and three uncles, three aunts were nurses. several younger cousins are practicing physicians today in the U.S. and Canada. All of them very well trained and several of them prominent in their fields. Three of them, my Dad, and my uncles Don and Jack, it's fair to say, were extremely prominent. They founded a clinic and one hospital in different regions that are still functioning today. My dad, though in private practice, published several papers in medical journals during his career. That is extremely rare today for physicians not associated with medical schools. The practice of medicine then was very, very different than it is today.
I mention this because I have definite opinions on how the U.S. health care problem could be fixed, and you should know my background because like everyone's, my opinions are heavily influenced by my childhood, education, and life experiences. So my preferred solution to the medical problem we face is obviously due to my background. I admit that. Sadly, however, I doubt we will fix our medical problem and do it well. We will do something for sure, we're forced to. But it won't be good, only less bad.
I am a advocate for capitalism. I could say of capitalism what Churchill said of democracy. It's the worst economic arrangement, but it's far better than any other.
You said, Government should be where the markets can't be or shouldn't be (like banking). This is key. And it gets us thinking about the proper role of government in health care and whether or not the capitalist model is suitable when it comes to health care. What defects there might be in the model, and how best to deal with them?
Consider just briefly, the capitalist model. Capitalism is an economic construct where capital and the means of production are in private hands. We capitalists get giddy just thinking about that. But we forget that capitalists hate free competition, they like low labor costs, naturally, and they want as little interference from government as possible, preferable none. Most importantly, they revel in monopolies and cartels.
(Incidentally, I've railed endlessly in these forums against conflating free-enterprise with capitalism, because in theory they have nothing to do with each other, and in practice they are opposites. If I read more more post about capitalism and free enterprise as if they were dancing hand in hand down the yellow brick road, I am going to scream and start throwing things! The only way capitalism can co-exist with free enterprise is if a referee is watching ready to send the capitalists to the penalty box.)
Now, consider health care in light of the capitalist model. To a capitalist, healthcare is the goose that laid the golden egg! Here you have a service that no one in their right mind would refuse. "Would you like me to repair your broken leg sir, our do you prefer to be crippled for the remainder of your life and suffer a great deal of pain?" "Do you want me to look up your rear end and see if there is a big lump of cancer, or do you prefer to chance it?" "Do you want this pill that will save your life? It will be a bit expensive, but keep in mind you can't get it unless you go through me, or others just like me, so don't bother shopping around. You're so sick now that I expect you'll be dead by the time you can make it to Canada."
If you haven't realized it up to now, the American model of private healthcare is a near perfect embodiment of a Cartel -- every good capitalist's dream come true! For the Cartel, the ever encroaching presence of government referees, the DEA and Medicare/Medicade enforcers, is a mere headache, but the Cartel could not exist at all were it not for government protection, and in this regard the FDA is key, because the majority of physicians make their living by writing prescriptions.
There are two health care sectors in the U.S.: 1> the private which is government protected, and to a lesser extent government regulated, and 2> the public, which is government sponsored and government regulated to a greater extent. The private sector does all it can to keep the public sector from growing and to hold the public sector referees at bay; a battle ever so slowly being lost, in spite of the private sectors cleverness and financial might. To the extent that either the public sector grows, or its referees blow their whistles in the private sector, profits could be lost, but this hasn't happened. Instead, and amazingly, profits and costs in both sectors are growing, and growing much faster than the GDP.
How is this possible? Obviously something is very, very wrong.
Although the one word answer implies a false simplicity: the word is "CARTEL." The Cartel must be broken and brought to its knees if the pattern of costs rising faster than the GDP is to be corrected. The way to break a Cartel is by introducing competition, or to use that favorite American expression: "Free Enterprise".
The probability of enough competition being introduced to break the Cartel is, however, minuscule. There was a recent attempt to do exactly that with the Obama health care initiative. And while some minor inroads toward introducing competition did survive, the major thrust in that direction, the public option, was killed, and is dead and buried.
The Cartels message never changes: it is always focused on fear and risk. But if we are to bring the rate of cost increases down to no more than the rate of inflation, and even then U.S. costs would remain the highest anywhere, we must break the power of the Cartel by introducing competition. There are many good and practical ways to do this, but I'm not optimistic.
I'm reviled by the alternative, socialized medicine. But I suppose that is because i'm a prisoner of my upbringing.
