Governments raise their money through coercion, and impose their will through policemen and soldiers. When we turn to it, we are turning to the sword. Maybe this method can't be avoided for some particularly intractable problems, but forward-looking reformers should hesitate to use it. Bureaucracies cost a lot, often fail to solve problems, and frequently make things worse. A third problem with government action is that it is insensitive.
Government acts through universal prescriptions, laws that apply to everyone.
It therefore attempts to regulate situations it does not know anything about. There are millions of different doctor-patient situations. Unless we study each one, we cannot make a wise and fair determination of the proper prices to be charged. For example, if you felt physicians were charging too much, your first step would be to look into the matter and find out what doctors' costs were, why they were charging what they were charging, and so on. A next step might be to approach physicians and try to persuade them to charge less.
