Before I start let me say I didn't post this in the "Narrator's Ready Room" for nothing. This isn't intended as a discussion if the Federation uses money or not (see below). I am just assuming they do and would like to ask you all the following question:
How much does a Starship Officer earn (per month) based on rank (or rating) and time in service?
For the sake of the argument let's assume that a moderate 24th century standard of living costs 1,000 credits (orwhateveryouwanttocallit) a month per person, including a nice apartment, dining out from time to time, occasionally renting a holosuite plus new clothes when you need them and a vacation now and again.
Any ideas guys?
Note:
Somebody might want to know why I am assuming the Federation uses money, even if on-screen evidence seems to point to a non-monetary society.
What got me thinking about this problem is that a non-monetary economy is AFAIK not a prerequisite for Federation membership. So what about a human Starfleet officer who decides to settle down on (for example) Bolarus after leaving Starfleet? What if they don't use money on Earth, but on Bolarus they do? Our ex-Officer will have lots of problems moving to Bolarus, if he doesn't have a single credit in his pocket and I don't think Starfleet would just tell him "Sorry man, but you can't live where you want, cause we are not going to pay you anything for your time with the fleet".
