According to the Commonwealth Fund (an endowment-supported US foundation), US healthcare spending has increased to 16.6% of GDP in 2014. Other countries have seen less rapid increases in healthcare spending. For the most part, inflation is being driven by doctors with a vested interest in pushing medical services, expensive treatments, and pharmaceutical drugs. To my surprise, what I’ve found is that many aspects of modern medicine aren’t supported by rigorous scientific evidence. While the FDA drug approval process superficially appears to be scientific, it often isn’t. One way that pharma companies game the system is to prove that a drug (e.g. statins) affects a dubious biomarker (e.g. cholesterol) rather than prove that the drug causes more good than harm (e.g. lower mortality).
Unfortunately, mainstream views on science and medicine are quite ignorant of what goes on. We are taught to only trust medical advice from “trained and licensed professionals”. Much of society worships technology and has blind faith in the claims made by medical authorities. I would argue that this environment is a fertile ground for the trend in healthcare inflation to continue going forward. And if that trend continues, it is likely that American health insurance stocks will continue to do quite well.
Pharmaceutical companies researching active placebos may also do quite well.
