Just obscene. I have taught Latin, English, and European History, including many classes at the AP and IB level, in private and religious schools for 20 years, and although I did manage to put together a small pension, I have never made a salary higher than $45,000 and have always had to have a second job. Currently, I work at such a school which is across the street from the local public school department of education headquarters. The fancy cars that come in and out of their parking lot would make your eyes roll. Again, just obscene.
When I was in high school, our principal worked as a farmhand during the summer with us teenagers.
