<p>There is wide variability in how much instructors and teachers work and make. I have friends who are tenured full professors at different Us. One makes over $100,000 annually at state flagship U and has a pension he will receive if he ever retires but has been at his job since the 60s and has co-authored many math and science texts and curricula that are used worldwide. He does travel extensively, making presentations and lives very modestly. He easily works over 80 hours/week and was bringing work for his editor to read while she was hospitalized! Another is an econ prof at a private U and earns a lot less but she doesn’t drive herself nearly the way the other prof does. Her private U has much lower caps on salaries, as it is a very small school with limited resources. She has gone on one sabbatical and is planning another. The public school prof has never taken a sabbatical in his decades of work. Our neighbor is also an econ prof at public flagship U; he also earns over $100K and has taken a sabbatical, does entertain in connection with work at his home & does seem to travel a lot and have long hours.</p>
