The individual's motivation and skills play a big factor in the equation. It is not the same if a person is a CPA with a solid MBA and then goes and gets a doctorate from a low tier school. Most likely, this individual should be able to get a job no problem given that there are tons of unfilled accounting teaching positions every year. The same can be said about IT, Finance and other fields in demand. However, one has to be realistic, you cannot expect to have a DBA, MBA and BS from low tier schools, little work experience, no specializations and almost no skills and then land a job as a professor. There is no shortage of people that can teach basic classes, the shortage is of people that can bring skills that take time to develop. There is also the online factor, many people come to the forum with no face to face education but yet want to find a job at a bricks and mortar. I would be hesitant to hire a person with only online degrees and then give this person an opportunity to teach a face to face class as most likely this person would have no clue about how face to face class work.
