Elvish Class Systems?

[Lomelinde]

This may be a rather inane question, but I've been curious about it for some time now.

Did a class system exist among the Elven communities in Middle-Earth? There were rulers, lords, and advisors to them, but were there also, say, middle and lower classes as well, or was everyone equal?

I know there weren't any financial issues to divide the Elves into consecutive "haves" and "have-nots," but did other societal traditions place some Elves above the others?
Were those who ran the kitchens and stables treated differently from those who served in the courts? In another words, did Elvish societies divide themselves into hierarchies like those of Men?

Although the answer is probably ambiguous, as Tolkien never (to my knowledge) said much on the subject, but it's still an interesting speculation.
