depending on research, prof probably make 100-300K, then those that do research can make another 100K in summer salary and then those that want can also be involved in side projects worth even more. there are other perks if one wants them too.. sabbaticals can be used create even larger amounts of income every few years and i would assume Su has a program for them to live on campus in dorm settings basically living for free for 2-3 years. I know some here take advantage of that, sell the car, and rent out the home and bring in 100K while living on the colleges dime.
There are also ones who live on the edge, dont do the research or are in a field that is very limited and are broke. Most of the ones i deal with are doing quite well, I know of ones who are flush enough they dont even cash their pay checks before the expire..
Who cashes paychecks? This story lost a lot of credibility with that statement haha
