In reply to GreenTongue (msg # 7):
While it's true I mentioned only one episode, that was mostly for the ironic coincidence of the casaulties from that one episode matching a US army unit "expected" casualty rate given identical size and deployment time.
But taken as a whole, the death rate for Star Fleet must be enormous, given all we see. Not only does the Enterprise, a "prestigious" ship, suffer far more than a contemporary wartime military unit, but we see entire ships (and fleets of ships!) wiped out, especially later on in the franchise.
One nice thing about Trekkies, they do the most geeky things, including statistical analysis of casualty rates, and they've done this one, to use a pithy phrase, to death:

It's interesting you brought up overpopulation. In one episode, one planet is suffering from exactly that problem. The solution achieved by the leaders of the planet is to acquire a deadly virus that Kirk just happens to be a carrier for and let it ravage their population. The Enterprise guys don't stop this. (In fact, by returning the infected "pretty girl", they aid and abet) No one raises a hand and says "Hey, there's an infinite frontier, why not just go move out?"
Now, there are other ways to look at this. One could say, we see a lot of deaths on the Enterprise but that is exceptional, most of Star Fleet is calm and quiet and safe. But if that is the case we run into two problems. First, seeing all those doomed ships through the episodes, we see that the Enterprise actually gets off easy. Second, if this was true... what would that do for morale on the Enterprise?
"Hey, I just orders for the Enterprise!"
"Oh my god... I'm so sorry."
Given what happens (so frequently) to Star Fleet, would anyone in a happy, utopian society, living a life of prosperity and peace, actually join?
