You've been proven wrong on this so solidly there is absolutely zero defense of your position.
The health care expenditures of other industrialized nations (ALL of which have some form of single payer system) are less than our expenditures. And many of them have highly competitive quality. In some areas (such as infant mortality) they out perform us.
It is you who have been proven wrong, on solid historical evidence of the inherent inefficiencies of central planning and monopolies.
Lower expenditures are because of centralized rationing, not because bureaucrats deliver more product for less.
Infant mortality is an irrelevant deflection, as there are numerous other factors that play into that statistic.
To prove the total lack of defensibility of your position, I defy you to name
ONE THING that the central government has taken over, were the costs fell as a matter of economic forces and the level of service increased beyond anything freedom offers. Just one.
Health care.
We can compare our system to that of every other industrialized nation.
The systems are all running in parallel, with the same level of health concerns, the same limits of medical science, the same expectations of health, health care, and health care distribution, the same drug companies, the same living conditions, the same understanding of sources of health problems, etc., etc.
You can't come up with a better comparison than REAL LIFE!!!
And, one of the central points is that OUR system is based on insurance companies working to maximize profit. In general, we love capitalism. But, health isn't a product that is fully susceptible to capitalist forces. Under capitalism, people get to freely make choices. But, if your doctor says you need to have a tumor removed, to have regular insulin injections, etc., etc., you can't decide that you'll buy another TV instead. It's just NOT a case susceptible to the downward forces on price that we might hope would come from capitalism. Get it?
