People from the commercial sector who believe they have some truth to reveal to the misguided people in higher education see themselves very much in the role of what Saul Bellow terms 'Reality Instructors.' The reality instructor is referenced in the marvellous Herzog, ("Moses was irresistible to a man like Simkin who loved to pity and to poke fun at the same time. He was a Reality-Instructor. Many such. I bring them out") but the character is a constant theme in Bellow's novels. It is usually manifest in a male, street-wise character who delights in teaching the main, intellectual character some truths about the 'real world'. But it's worth pointing out that the main character is aware of this, enjoys it, and that these truths are rarely as valuable and as robust as the reality-instructor believes.
