Bruce Murphy reports that the average salary of a full professor at MATC is more then $ 91,000, far more than the average at UW and, I think it would be safe to say, Marquette. The instructors at MATC have a higher teaching load (although, at least in the academic areas, they teach at a far more basic level)but have no expectations with respect to research and are, not to put too fine a point on it, generally (maybe even universally) less credentialed and accomplished than profs at the universities.
Murphy notes that MATC operates "under the radar" but much of the nuts and bolts decisions made by other units of government also draw little attention. More fundamentally, he suggests that one of the reasons for this bizarre salary level is that MATC has a source of revenue, i.e., its ability to levy a property tax, that the UW does not have. The absence of additional revenue, in other words, has limited salaries at UW. Costs at MATC have expanded to consume the "available" money.
