Doctors have higher average IQs than their patients. Society gives doctors halos to wear. Few would argue with the assertion that power corrupts. Few would even suggest that there are exceptions. Doctors are empowered both by their superior intelligence and the status society affords them as well as by advantages given them government.
So, given that power corrupts, it stands to reason that doctors on balance are more corrupt than others in business. Go to an emergency room or even an office visit these days and any doubt about their being corrupt will disappear. Emergency rooms no longer even hide their goal of cleaning you out as completely as is possible. Treatment is not even a close second in terms of goals.
Unless you have a condition beyond what a smart high school student could diagnose, the doctor will collect a fee and send you to a specialist. Chances are the specialist will see your complaint as elementary, do nothing for you and collect a huge fee. Medical professionals have become what economists call rent seekers. The market they work in is rigged in their favor and they have convinced themselves that society owes them just for being who they are, independently of any work they might end up doing.
When a business can only charge what the market will bear, attitudes towards customers improve markedly. The healthcare market is rigged in favor of providers and patients routinely get gauged mercilessly. Treatment and cures are highly illusive unless it is for something you could diagnose yourself.
When Obamacare gets rolling, things will only get worse.
