Tenure track professors get paid pretty well, adjuncts get paid like Scientology staff.
If that $60k is actually his salary, that's not great. Now, if one of the other commenters is right and he's at UT Arlington, $60k is a perfectly liveable income here, but any professional job with more than a few years experience is going to surpass that. As a software engineer in the same metropolitan area with about 6 years experience, I make $66k/year. I'm not even that good, and I'm probably younger than him.
