I would say as a rule of thumb: It all depends on the two parties involved, on their individual attitudes and Character. For instance, I have been with a few women who were insecure within themselves and would assume that I thought less of them or was critical of them when I was not. Its just that they knew I had the greater intellect and therefore thought I thought less of them, but this is probably what Jung called projection. This is what they thought of themselves by comparison and therefore thought I would come to the same conclusion, which I did not. I would say the success of a relationship depends on peoples self worth and levels of growth, not on what they do, or how much they have.
