I thought the reason (main reason) Lien's character was dispensed with was they were bringing Ryan onto the show (a move I agree with), and for budget reasons one of the existing main cast members had to go. Wang had just receives a magazine award which gave the show visibility (but which did nothing to increase Wang's acting ability), so by default Lien was fired.
The fact that the writers seemed to have trouble figuring out what to do with Kes probably didn't help Lien's chances.That what Roddenberry initially did with LaForge, and TOS had the Asian driver, and DS9 often had the woman driver.
Not sure what point you were trying to make.Compare this with the story arc on nuBSG where the ships completely run out of all food and people start to starve, get too weak to move, and are in physical pain.
There's one scene in the pilot's bunk room where one of the pilots is at the point of death, and the other pilots scrape together the last of their food, which amount to about one cracker worth of crumbs, and feed it a pinch at a time into the starving pilot's mouth.
I haven't seen nuBSG for years, and that scene is still vividly with me.
