Since there are various countries, such as Canada and Britain, that have the kind of government-controlled medical systems that some Americans advocate, you might think that there would be great interest in the quality of medical care in these countries.
The data are readily available as to how many weeks or months people have to wait to see a primary care physician in such countries, and how many additional weeks or months they have to wait after they are referred to a surgeon or other specialist. There are data on how often their governments allow patients to receive the latest pharmaceutical drugs, as compared to how often Americans use such advanced medications.
But supporters of government medical care show virtually no interest in such realities. Their big talking point is that the life expectancy in the United States is not as long as in those other countries. End of discussion, as far as they are concerned.
They have no interest in the reality that medical care has much less effect on death rates from homicide, obesity, and narcotics addiction than it has on death rates from cancer or other conditions that doctors can do something about. Americans survive various cancers better than people anywhere else. Americans also get to see doctors much sooner for medical treatment in general.
Talking points trump reality in political discussions of many other issues, from gun control to rent control. Reality simply does not have the pizzazz of clever talking points.
