The glut of PhD's is at such a level that the last teaching jobs available to industry professionals have all gone to boomers who will stay at those jobs until they die.
I teach at a Vocational college the teaches entry level system administration.
I am one of those boomers (1959) but I have no degrees above a Bachelors. I could not get out of the teaching because of ageism and assumed if-you-cant-do-teachism.
I took this job 15 years ago because prospective employers looked at my then
30 year career and repeatedly said you cannot adapt to new tech and are too expensive. So I took my sysadmin, programming, and management skills and taught them to younger people who did get the jobs I was rejected for. Hopefully some of my work ethic will have rubbed off on them and when they hire they will do it with less "ism".
Now I get to play with the newest tech and teach it.
