I look at this from a spiritual perspective. Everyone has natural gifts, and I believe these are given for a purpose. So the ideal field of study is one that develops the person’s abilities. For some people, this simply means going to a vo-tech high school and learning a trade. For others, it is a narrow, focused discipline requiring rigorous training, such as medical school. For others, it is a wide-ranging education in something like history, that trains the student to see patterns in historical events that can help him identify and solve modern problems.
There is no one size fits all approach to education.
