"I find this very puzzling because it's a solution to a problem that doesn't exist," Livingston said. "The purpose of college professors is to help students think. We help them by presenting divergent perspectives. Sometimes we believe those perspectives, but a lot of times we don't. We just need to present our students with perspectives so they can think them through and understand them."
The problem most certainly exists, but the proposed solution is worse than the problem. Having professor slaries based on the numbers of students willing to take their classes and/or student feedback might help, but might contribute to grade inflation whihc is another problem. You'd need to divorce grading from instruction somehow to combat that, which should be doable for most freshman and sophmore level classes, so at least the damage of inappropriate bias would be limited to those taking courses beyond the general requirements.
