Haha. There was a piece in the paper not too long ago (just before I came over to SIngapore) about their actual teaching wages, the averages amongst academics. There was a big debate about it, mainly because they were so much lower than those in practice, yet traditionally it would be the best in the class who would stay on to be academics, the very top. Anyway I think the average for a professor, from all subjects across the board, was 60k ... that doesn't take into account any money from books, or anything else other than teaching.
