As American Medicine advances further into finding cures for just about everything, fewer and fewer mainstream people can afford these advancements. One powerfully successful cancer drug costs up to $ 100,000 a year but can only extend the lifetime of a cancer patient a few more years. American Medicine is looking more and more like a war between Drug Marketing firms, Doctors who want to save their patients at any cost and the public who want to feel better vs. Insurance companies and Doctors really looking at the cost/benefit ratio.
The cost to develop novel drugs is so high that many drug companies are working to extend the patent rights for their already successful drugs.
Because of the American for profit health care system publically traded drug companies are mandated by their share holders to make the maximum dollars from any drug produced. Until America goes toward a European style National Health care system health care companies will charge as much as the market will bare to keep America healthy.
