I have my doubts about this - as a previous poster mentioned, ego is a huge part of it, so my suspicion is that you are going to get a pretty extreme bias when you let people self-report on this.
Around me, I do not believe 9 out of 10 people I know are "completely" or "mostly" satisfied with their jobs. The number if substantially less.
