But there is some historical informations, and as i am not from US i do not know if they are right or wrong.
Market mechanisms tend, by adverse selection, to penalize the elderly and those with chronic diseases, health is an attribute that determines the possibility of consumption of all other goods and services, we have information asymmetry between service providers and consumers, the existence of externalities, ie the fact that the use of some services produces benefits not only for those who get them, but to society as a whole, the occurrence of moral hazard; induction by supply and demand nature potentially infinite health needs before the finite resources to meet them.
Another thing that complicates things is that in health the incorporation of technology does not reduce the overall costs of labor or, what it does is increase the required number of specialists in addition to the direct costs of the new procedures. But the most important factor in spending growth has to do with the very model that focuses on medical and hospital care, and that thing that ever I mention with a topic we have a process that converts any medicalization of depression and anxiety disorder. The various settings of the U.S. health care system some ancaps complain because they think it would be nothing more than a means of precluding competition emerged in reality because these costs were exploding. The deal, as I said, is that the preventive approach, which is beyond the logic of the market, is much more efficient, as evidenced when comparing data between countries.
Let’s talk about the case of the U.S. then to understand how the system where he came.
In the early twentieth century, the richest people was attended by private doctors and private nonprofit hospitals through payments made by direct disbursement while the poor used hospitals and clinics, where they were met by teams of medical students. Insurers and plans Blue Cross and Blue Shield, developed later in the 1930s, practiced uniform rates for all members and served as the middle option. In the 1960s, with the population aging and already some tensions socais, there was a significant government intervention in the health sector through the creation in 1965 of the Medicare programs (federal) and Medicaid (state governments). These programs are compatible with private insurance and initially preserved the system of payment per service (fee-for-service). The medicare is one that serves the elderly and disabled, and provision of services is primarily through insurance companies contracted by the federal government (ie, well within what you said). The Medicaid for the poor is that it and the provision of services is done basically by community centers, medical schools and hospitals. You mean that greater state intervention did not mean a change in the private logic of the system, she came to cover a hole, complement and not stifle the market.
And by the eighties / ninety had an explosion in health care costs so that there is a large gap between them and the family income, and there came many of the regulations. These high costs have to do with an “over-treating patients,” coordination failures and moral hazard and adverse selection here may be the difference between life and death. We know that regulations are sources of costs and could mean a less competition but we can not make the mistake of thinking them evenly to understand how it came that way a new market for capital appreciation, where the financial system and in all "quasi-markets "capitalists, assumed responsibility for financing the supply and demand. The scheme used was the securitization of risk, in which a portion of the population is directly or indirectly, through taxes, financing costs. The goal was to give support to the practices of the medical-industrial complex that had formed and dominated the dynamics of health systems.
In this context, increasingly, the mechanisms of capital accumulation began to be ordered and governed by financial capital. Hence the need to contain medical costs and promote the intensive use of technology. New management practices (managed care), such as budget control, business development and control of pharmaceutical benefits offered were incorporated, with increasing impacts on the evolution of the system. So I insist that the current state of American health care system, despite the post-Obama deserves a separate discussion, represents a new stage of capitalist development in the area of health, the financial capital aims to become hegemonic.
This is capitalism, and irony of ironies, at various times I feel like the biggest supporter of this system. What legitimizes capitalism is largely innovation and a true capitalist therefore try to defend the American health care system (with some criticism of some over-regulation here and there, but not to the system as a whole), as the great debate in health between public and private is not about to turn back there because of an absurd idealization of the past, but between innovation and fairness. This innovation, which naturally has a lot to do with the existence of intellectual property rights (forms of monopoly).
