The increased costs of health care are primarily related to malpractice insurance and the increased cost of drugs (whose profit margins are not razor thin, but fatter than Star Jones - look at a Pfizer quarterly earnings report sometime).
Uhh...
Malpractice Insurance rates correspond to the rate of Malpractice Tort suits. Do you think I am stupid. Insurance rates rarely go up on their own, there is a cause and effect relationship...
OK. Pfizer is doing great. That may be why they have canned thousands of workers and have shut down facilities all over the nation. How about the five or six other major drug companies that were around a decade ago, most are half of what they used to be. Costs attributed to lawsuits are directly to blame.
On the average drug it takes six years out of the seven in the no-compete pahse of the release to recoup costs. If a drug company fails to find a hit once per decade they are pretty much done. Surprisingly, the majority of these costs are not R&D related - they are related to insurance, lawsuits, legal consultation, and government regulation.
