Two thoughts come to mind:
1. Trial lawyers make lots of money from fees in medical malpractice suites. What is the profession of most of the members of Congress?
2. While I have no basis for this, I am of the opinion that many of the "excessive" malpractice awards are awarded by juries. If the juries stopped awarding such high damages, perhaps the cost of medical malpractice insurance would decline. I suggest that the high awards by the juries are the result of a desire to "teach the doctor a lession." Of course, it is the insurance company that pays.
