You got an example of such a professor? The highest salary in the English department is about $140k. The highest in Accounting is ~$225k.Add to that inflation factor the cost of Liberal/Progressive professors. A professor receiving $450,000 +/- for teaching one course is ludicrous! Who has to pay for that? Students/Parents!
Yes, there are some professors with light teaching loads. They are usually professors with large research grants subsidizing their work, or perhaps they have an endowed chair. In some cases a university will make a low teaching load part of a package to get a high-profile faculty member. And in some cases faculty will get a temporary reduction in teaching load so that they can work on a research project.
Trust me--Of all the factors driving tuition increases, faculty salary is pretty low on the list. You know how enrollment has skyrocketed? Instead of hiring a lot more faculty to teach all those additional students, universities just enrolled a lot more graduate students, let them teach all the scut classes, leaving the faculty to teach just the upper level courses. If they need additional instructors, they turn to part-time faculty--and I can guarantee you that their salary isn't driving tuition up at all.
