Are Ph. Ds in engineering worth it? I don't want to teach at a college, so that isn't what I am going for, but in general, in the field of engineering, are they worth it?
Besides, in Engineering & at good universities the direction of money transfer is often from university to student. You get fairly decent stipends, though never as good as a "real" job.The advanced degree is not just a way for the university to suck additional money from the grad student.
I suspect it's the other way around: The vast majority of engineering PhDs end up *not* teaching, no different than any other technical field. The same mathematics that makes so many HEP physicists complain at this site about not being able to get a job in academia applies to engineering. Tenured professors supervise ten or so PhD candidates over the course of their career. Only one is needed as a replacement. Another one *might* get a career in academia due to the growth of academia. The other eight or so? They don't get a job in academia. They have to look to government and industry for employment.You absolutely need a PhD to teach anywhere reputable, but that's not what a PhD is solely good for, and the vast minority of PhDs end up teaching.
