One of the big claims for government-run medical systems is that they can "bring down the cost of medical care." But anyone can bring down the cost of anything by simply buying a smaller quantity or a lower quality.
That is why countries with government-run medical systems have waiting lists to see doctors, and even longer waiting lists to see specialists or to get an operation. That is why those countries seldom have as many high-tech medical devices as in the United States or use the newest medications as often.
In those things that are crucially affected by medical care, such as cancer survival rates, the United States leads the way. In things that doctors can do little about -- such as obesity, homicide or drug addiction -- Americans shorten their own lives, more so than people in other comparable societies.
