Well, what is the population of Earth in say 2399 Picard time?
Billions?
Hard to say! We know that in 2258 of the Kelvin Timeline, Vulcan had a population of six billion; and we know that in the alternate timeline in which the Borg were successful in preventing First Contact, the assimilated Earth has a population of approximately nine billion drones.
I would be inclined to assume, on those bases, that a population of between six to nine billion humanoids is most common for technologically advanced species homeworlds. But that's pure conjecture on my part.
Alot of the humans in Starfleet seem to be from Earth, and not a colony, etc.
I mean, Starfleet in the 2250s is comprised of over 7,000 ships, and I'm sure there are even more by the 24th Century. Of those, we have gotten a good look at exactly 15-20 or so crews. That's not much of a representative sample. I would not say we've seen nearly enough of Starfleet to really have a sense of things like how common Earth origin really is.
You guys are talking about real estate and I'm still struggling with why Lower Decks crew have inferior replicators to the senior staff, and why they have to live in a corridor. It must be some deliberate choice to encourage advancement in Starfeet, yes?
I think that's part of it. Part of it is probably to build resilience in Starfleet officers and crew who need to be able to operate in extreme conditions under extraordinary circumstances. And part of it is probably just that even in the 24th Century, starships have limited resources.
Again, Starfleet is rigidly hierarchical in a way that Federation society at large probably is not.
I agree. Picard seems to come from a good family. To me he 'feels' roughly equivalent to what today we would call upper middle class (and his family having been there for a long time), but no more than that.
Yeah, and I think it's likely that the overwhelming majority of people either live in comparable material conditions or have access to comparable material conditions.
Kirk, on the other hand, felt more like a self-made man to me, who worked his way up because of his sheer aptitude for the job. (That's from before it was established his father was a captain, too, though).
For the record, we don't actually know that George Kirk became a captain. We know that he had achieved the rank of lieutenant commander and the billet of first officer of the USS
Kelvin under Captain Richard Robau in 2233, but we have no other information about his career. It is entirely possible that Lt. Comm. Kirk never advanced past that rank or billet and retired from Starfleet after Jim was born. Or it's possible he kept getting promoted and achieved the rank of Fleet Admiral! Who knows? There's absolutely no canonical info.
I kind of prefer the idea he never advanced past lieutenant commander/first officer, though.
