I thought of this as I read the discussion about Harry Kim in the Voyager forum. The various Trek series have a rather mixed legacy when it comes to promotions for members of their crews.
The TOS crew was probably the highest ranking, but it largely took them 30 years for many members to get many of their promotions despite their heroics. By the time of The Undiscovered Country, the lowest ranking crew member was a full Commander with four members being captains (I'm not sure if McCoy made captain by ST VI)
The TNG crew seemed to have the most well rounded careers. Even excluding the movies, during the seven year run of the series, Data is the only character to neither receive nor be offered a promotion. Everyone else rises at least one grade during the series. Both Picard and Riker are offered promotions and turn them down.
DS9 also has good legacy of promotions. Sisko, Dax, Nog, and Dr. Bashir all receive promotions during the series. As does Kira in the Bajoran Militia. I'm honestly not sure about O'Brien since his actual rank is never stated on screen. It's possible that he is the highest NCO possible in Starfleet and I believe that he stated at some point that he had no interest in receiving a commission of his own.
Voyager had a rather poor track record of promotions. The only person that actually receives a promotion is Tuvok. Tom Paris has the dubious distinction of being the only person during the course of a seris to actually receive a demotion...only to have his previous rank reinstated. There is no good reason for the lack of promotions on the show. Even if e everyone kept their same position, there was no reason not to promote them. One wonders why exactly did Tuvok get a promotion and why no one else?
Enterprise is a mess. Apparently, Hoshi and Travis stay ensigns for over a decade. In fact, does anyone on the show get promoted? Now I'm willing to concede that the United Earth Starfleet might have a radically different approach to promotions than the Federation Starfleet. It was less of a military organization and more like NASA. Thus rank may not be nearly as significant as it is in later series.
