I think the root issue is that Medical treatment existed before the scientific method. This creates a huge industrial debt of "doing things the old way" and relying on authority/tradition.

I can only imagine deregulation is the solution. At least in the United States, medical is run by various cartels/factions. It would be nice to have input from scientists rather than authority.
