<p>Interestedad, your calculation that a class with 100 kids and one professor is less costly than a class with 12 kids and one professor assumes that they subject is Renaissance Literature and that the classroom is an auditorium with chairs and a blackboard.</p>
<p>Try visiting a class on Nanotechnology with those same 100 students in a state of the art laboratory, where the 100 kids break off into groups of 10 using equipment which went “live” a week ago… and your math breaks down pretty quickly. Your arguments are nice but don’t make a lot of sense for most of the scientific disciplines where capital investment in labs, buildings, and the actual research that takes place there is a much higher, fixed cost than the variable cost of adding a professor or two.</p>
