One of the strongest talking points of those who want a government-run medical care system is that we simply cannot afford the high and rising costs of medical care under the current system.

First of all, what we can afford has absolutely nothing to do with the cost of producing anything. We will either pay those costs or not get the benefits. Moreover, if we cannot afford the quantity and quality of medical care that we want now, the government has no miraculous way of enabling us to afford it in the future.

If you think the government can lower medical costs by eliminating "waste, fraud and abuse," as some Washington politicians claim, the logical question is: Why haven't they done that already?

Over the years, scandal after scandal has shown waste, fraud and abuse to be rampant in Medicare and Medicaid. Why would anyone imagine that a new government medical program will do what existing government medical programs have clearly failed to do?

If we cannot afford to pay for doctors, hospitals and pharmaceutical drugs now, how can we afford to pay for doctors, hospitals and pharmaceutical drugs, in addition to a new federal bureaucracy to administer a government-run medical system?

Nothing is easier for politicians than to rail against the profits of pharmaceutical companies, the pay of doctors and other things that have very little to do with the total cost of medical care, but which can arouse emotions to the point where facts don't matter. As former Congressman Dick Armey put it, "Demagoguery beats data" in politics.

Economics and politics confront the same fundamental problem: What everyone wants adds up to more than there is. Market economies deal with this problem by confronting individuals with the costs of producing what they want, and letting those individuals make their own trade-offs when presented with prices that convey those costs. That leads to self-rationing, in the light of each individual's own circumstances and preferences.

Politics deals with the same problem by making promises that cannot be kept, or which can be kept only by creating other problems that cannot be acknowledged when the promises are made.

Price controls are a classic example. At various times and places, in countries around the world, price controls have been put on any number of goods and services-- going all the way back to the days of the Roman Empire and ancient Babylon. Continued...
