Doctors should be paid for preventing sickness or disease. When people get sick - that's when doctors should be footing the bill!
Our society has it backwards and that's why society abounds with sickness, and that's why medical prices are skyrocketing. When you focus on treatment of sickness, then, because of high technology that's used, which continues to become more sophisticated, it always costs more. For example, the "Obamacare" solution is 97% about treating sickness. How pathetic!
Were the emphasis on preventive treatment, medical costs would plummet!
Torah is light. Torah is truth. The Torah way to practice preventive health is detailed in Maimonides (Hilchot Deah, chpt. 4).
Were people to abide by Torah's laws, medical costs would be negligible, people would live longer, would hardly get ill, will take time to exercise, eat well, sleep well, and one's perspective would be positive and rosy.
How do we know prevention is Torah's way of practicing medicine? It says so clearly in Rashi (Ex. 15:26), "God provides you with Torah and its commandments so that you should spare yourself of diseases, as the doctor says to the person 'Don't eat that which bring you back to illness'...". Clearly, Torah's way is the preventive way.
