Prices determine how resources are to be used. They are also the means by which products and services that are in limited supply are rationed among buyers. The price system of the United States is a very complex network composed of the prices of all the products bought and sold in the economy as well as those of numerous services, including labor, professional, transportation and public-utility services. The interrelationships of all these prices make up the system of prices in which everything seems to depend more or less upon everything else.

The cost of medical care in the United States is very high. The time and money that doctors spend on their medical education are probably one reason for this problem.
A visit to a doctor’s office costs people from fifteen to fifty dollars. It is impossible to pay for the medical care they need. Many people in the United States think that doctors are overpaid. Most doctors, however, disagree. They say that they Were required to study medicine for a long time. Tuition for many years of medical education costs a lot of money. And young doctors need a lot of money for their work. So, they charge people high prices for medical care. Therefore it is possible that the high cost of medical care in America is unnecessary. Because high tuition is one cause of high costs, one way to lower costs would be to have medical schools that are free or have low tuition.
