In other words, will professors find the possibility of making extra $30k exciting enough to change their attitude? If the answer is no, then perhaps this is not a very good way to bring more niceness to the classroom. Even if the answer is no, this can still have a positive benefit. Profs with an extra $30K might use the money to be more productive (i.e., by hiring extra researchers). More productive profs are more likely to succeed in academia and thus more likely to select profs with similar values when their department hires new faculty.
