Overall, I would argue that on the demand side, the United States healthcare system is essentially socialized. The fact is that close to 90 percent of health-care spending is paid for by third parties, which means that individuals in this country generally experience a socialized process for obtaining medical services.
I am inclined to lump private health insurance in with government programs, and call the whole deal socialism--even before Obamacare tightens the noose on insurance companies any further. If we had truly unregulated, unsubsidized private health insurance, then I would look at it differently. But if we got rid of the subsidies and regulations, I am pretty sure that private health insurance would scarcely resemble what we see today.
On the other hand, Romesh Ponnuru argues that in the mainstream media, the facts do not matter. I think he makes a solid case that the media tend to report left-leaning analysis as fact and portry right-leaning analysis as biased or misleading.
