I personally believe that we should only need a doctor during times of war and in the case of trauma or injury.
Green smoothies do not cure gunshot wounds.
That probably cuts out 90% + of all the illness in America today. The other stuff can be cured with proactive habits, including diet and exercise changes and the introduction of positive thoughts into the mind during everyday activities.
Nonetheless we, as in the Western world, need to slowly phase out our current uses of allopathic medicine, which are just as useful as the alternative "natural" stuff but in different contexts, and replace it with increased emphasis on education of the public on healthy foods and natural health. Not cures, but health. Focus on the positive.
Of course, in the Western world, resources to acquire such things are available to everyone. They just have to look. Steps should be taken in education to more aggressively promote the mindset of health and to feed children with proper knowledge and the experimental mindset that allows people to find out what's best for them rather than accepting the doctor's will as God's.
Yes, let us feed children. Har har.
To me, this is a very clear issue, and these ideas will probably result in me changing my future career from medical research scientist to...something else.
