@CM - look at all the disciplines it takes to keep society running today. Electrical Engineering, Mechanical Engineering, Civil Engineering, Software Engineering, Family Practioners, Specialist doctors in all kinds of fields from Surgeons to Endocrinologists, Dentists, Vetrinarians. These are just some of what makes the world as we know it possible. And not everyone is cut out for the farm or for the technical fields. You must leave room for the artists: poets, musicians, painters, writers, composers. Without them there is no entertainment and no books to read (remember, *nothing* fromt he outside world: not books or movies or TV shows).
