I've seen this survey previously. Unfortunately it is focused only on the monetary side of it.
I'll summarize it.Hell and Bliss simultaneously.
Teaching full-time gives me time to work on my craft; practise and performing. I believe this to be one of the most important aspects; how can one teach effectivly if we allow our own ability to atrophy? The life of a musician is life long learning.Honestly, despite the stress, I would never change my job and hope to continue until my last days. I often joke with colleagues that I would keep teaching even if I won the lottery or came into a win-fall; the only difference is I would immediately sack the time-wasters.
