Hmmmm. WEll teaching positions mean lots of teaching. Like maybe 4-5 classes per semester or more. Maybe 2-3 preps (different classes)
Salary can vary widely---small community type college can be as low as $40-50K WITH a PhD. Others schools that are large institutions AACSB accredited can pay $100k+ with an PhD depending on the school. AACSB accredited schools have to have a high number of PhDs, so teaching with just an MBA is not always an option. A teaching position with an MBA might max out at around $60-75k.
I have a friend at a large state "teaching" school with an MBA program, he is at $130+ as an assistant w/tenure--he teaches 3 and 3, I believe. No summer support.
Research schools (for instance, with PhD programs) invariable pay much more, however. But you are expected to be very productive in research. But even a research school will sometimes employ fantastic teachers, generally non-tenure track.
Hope that helps
