From The Student Whisperer by Oliver DeMille and Tiffany Earl:

Gallup reports that about 80% of people aren't happy with their work and life path...  Education has failed such people.  Indeed, based on this statistic, around 80% of us are under-educated - or mis-educated.  The years such people invest in studying and making the grade did not lead to make the choices or acquire the knowledge, skills, habits, and abilities that facilitated their happiness, fulfillment and meaningful contribution.  Is such a process, therefore, perhaps mislabeled?  Is this really what we want from "education"?
