Free market-style health care delivery systems have existed and no longer exist because they do not distribute their services in a manner that is socially acceptable. Continually arguing for their reapplication based on dogmatic non-empirically based heterodox economics (free market fundamentalism) is madness.
I refuse to follow anyone's macroeconomic plans that do not use empirical data and deny the existence of market failure, which is exactly what market fundamentalist systems require.
To be frank, I don't give a damn what you consider to be "socially acceptable" (which, in and of itself, is a loaded term that is inherently subjective and unquantifiable). You are attempting to justify what amounts to armed robbery on a grand scale on the basis that simply because the robbers consist of a mob of people rather than an individual, that it somehow excuses rank criminal behavior. If you liberals think that a free market health care system can't possibly provide for people in a manner that *you* consider to be socially acceptable, then feel free to put your money where your mouth is and start a charity to help people.
