Phase 3 trials for FDA approval of new drugs constitute 90% of the cost of new drugs. With drugs being the primary method of advance of health...we can safely say that the FDA is trying to compete with the communists in terms of deaths-caused by prohibiting already-known-to-be-safe drugs from entering the market.
As per my normal...most of the cost issue in the US medical industry is government-granted monopoly. FDA for drugs. AMA for doctors. Kill those monopolies, and even the most idiotic system of health-care ever built: (employer-provided first-Dollar insurance -- the US standard) would nearly be cost-effective. But it's hard to be cost effective when the government is doing everything in it's power to keep the cost of medical care high.
