The adjunct role is a trap. You keep teaching because you are hoping for a full time gig but these jobs become less available and ask for more. Once you have 10 years of teaching experience, you are hesitant to take a job as a salesman or technical support person as you would need to start your career all over as few will consider you for senior positions once you have 10 years of teaching experience. On top, you need to get a doctorate so you can keep getting jobs. People with full time residential five year programs are struggling for full time positions so at some point the adjunct loses hope and it is in survival mode, then the Azteca, UCN, CLEA or Da Vinci doctorate becomes attractive because it is not about impressing people but just about surviving for the next gig to happen. I agree that makes more sense to open a landscaping company or to drive a Uber vehicle, but once you have the degrees is hard to give up the adjunct career for opportunities that do not require education. It makes no sense to get a PhD to make 60 or 70K a year teaching on a contract basis but it is what it is.
