Public health is completely collectivized and many of its practitioners are more interested in politics than medicine. From Allan Stevo at lewrockwell.com:
“Data-driven” is a buzzword even in public health. Public health is the Marxist step-brother of the individualist field of medicine and generally unconcerned with an honest reading of available data. This moment in time makes that abundantly apparent.
Public health offers collectivist plans to address health, which is an individual concept. The medical field is becoming increasingly affected by the same. However, at its core, the medical field is not collectivist. Doctors focus on the individual patient. This can be traced back to the 2,400-year-old Hippocratic Oath and other texts on medical ethics. The public health profession can trace its roots back to the late-1800s in England as ideologies intending to push a supposed collective will on others grew in popularity with some intellectuals.
As such, every single pronouncement from anyone in public health should be given the same skepticism that you would offer a pronouncement from Karl Marx himself.
