1. The structure of an unstrained free-market medical system is well-suited for rent-seeking rackets. Doctors and hospitals tend to be monopolies. Even with competition, few are
competent at choose between competitors, etc. This situation has historically been restrained by modest regulation and by the fact that most people entering health care are motivated by the desire to help others. These restraints are
gone.
2. The current situation is neither "over regulation" nor "under regulation". It is mis-regulation. But all the regulation or lack-of regulation in the world won't really prevent a determined group of racketeers/rent-seekers aiming for their accustomed level of sales and profits through their monopoly position. There just aren't enough honest dollars in health care to incentivize the currrent system into being efficient. Making the existing system "work" is akin buying La Cosa Nostra spreadsheets and hoping this will turn it into an honest business. Reform at this juncture is like saying "can't you only restrain the growth in fraudulent loans just a bit". When the housing bubble was high, even the growth couldn't be stopped. Now, the decay can't be hidden.
3. It's not "The Doctors" or "the insurance companies" or "the hospitals" that are the problem but all of these and none these. There are indeed "good parts" and "bad parts" in the drug, hospital, doctoring and insurance industries. But the "bad parts" are far to too adaptable for efforts at restraining them piecemeal to work. From the chart in the article, you'd have to deduce the parasitic parts of US health care get at least twice the sales of the parts needed for a sane health care system and quite possibly four or five times that.
4. The point is NOT how we will correct the excesses of the current health care system. The question is when the growth of the current excesses will reach the point when they are truly unsustainable. The current "reform" wave seems aimed to enlisting the state primarily in the task of squeezing more money out of those who weren't paying into the racket (the uninsured). Well, once they've run of people to squeeze and health care cost go from 20% to 30% of GDP, there won't be any further place for the cancer to go but down. I'm guessing that's five to ten more years. Will our economy last that long? We'll see.
5. There are free market solutions that could work and single-payer solutions that could work. It's shame we won't see either kind of sanity for a while.
