The idea that people write books simply for the joy of writing them is nuts. There was some kind of compensation. I'm guessing (again) that it wasn't enough to pay off the mortgage on his house, but I'll bet it was more money than I earned last year.
I think you missed my point (or I didn't express it well). I wasn't saying that he shouldn't receive money for editing his book. I was just wondering why this thread seemed to be consumed by a discussion of DiPiro.
