When Macmillan's CEO John Sargent laments that «the value proposition goes ever downward when on screen...
the perceived value decreases without a physical object,» I think what he's really saying is that publishers can't rip readers off for paper any more.
Attendance increases, the quality of student work vastly improves, and failure rates and discipline problems
decrease significantly, if not altogether, as students
perceive value in what they're being asked to do.
