Hmm. Okay but the problem with the supply/demand argument I think, is the availability of a reasonable substitute. Meaning, PHP5 with CodeIngitor is just as capable of creating sophisticated apps as Ruby on Rails, and thus it is a low cost replacement for RoR. Thus, shouldn't one place downward pricing pressure upon the other? I'm taking this from Porter's 5 Forces model.
So there must be another element to the equation. I like the point about .Net separating wheat from chaff with licensing cost. Yes that is probably also a factor - perceived quality. PHP does have a perceived quality issue.
