I have a nephew who graduated from Harvard Law School about ten years ago. He could have taught law, but he didn't. Instead, he's working for an international corporation and pulling in a salary even I couldn't believe. I mean, he's my nephew, and he is making more than half a million a year as salary. Let's just say he's doing fine. He never considered being a professor.
I have one currently presenting his PhD thesis at Harvard !
