Matthew Crawford, an author and motorcycle mechanic who holds a Ph.D in political philosophy, provides an interesting perspective on the quality of work. He contrasts the Dilbert-like drone life in a cubical, or in middle management, versus motorcycle maintenance. I'm not sure what's up with the ubiquity of motorcycle repair as a metaphor for everyone good, but the author certainly has a point.
It would be a huge mistake to view education that does not explicitly lead to something like motorcycle repair as bad training or a waste. Dr. Crawford himself is an example of someone who earned a lot of education and ultimately found his way.
