A quote from Henri Nouwen’s Creative Ministry:

If teaching means providing man with enough academic weapons to outdo his fellow man, to make more money, to have a better career, and more esteem in his neighborhood, we had better start asking ourselves if there is any word from God that supports this approach.

I think that education has become too stratified.  It is hard to justify studying something that you don’t intend to make money from… people wonder why you’d bother.  It is hard to get into many areas of study because there are barriers set up to make it available to only a few.  And it is difficult to find someone who wants to teach in the old-fashioned apprentice-mentor relationship, which can be more hands-on and effective.  (Plus both people benefit from that arrangement.)
