I can see a sucker for late night infomercials... for just pennies a day!
Edit: Take a closer ponder at the graph I posted. Try to understand its meaning and why it is relevent to this discussion. Players may be on the Zone-B threshold for a variety of reasons.
Edit: "2 minutes a week" is the bare minimum required for the upkeep of a minimalist carrier that a typical owner that is on the threshold (Zone B) of buying one can afford. If they take a break for 6 months they might lose their carrier. A mediocre carrier (1 Billion per year upkeep) has a weekly upkeep cost of 19 million per week. None of this is an issue for a player confidently within Zone C.
I think I've figured out your misconception.
You're thinking, "Fleet carriers are expensive, and upkeep is a reasonable percentage of the cost of a fleet carrier, therefore upkeep must also be expensive."
The issue is in the basic premise. Fleet carriers are
not expensive.
I'll say it again; fleet carriers are
not expensive.
Getting the capability to earn a fleet carrier is expensive. Learning
how to get a fleet carrier, to make money rapidly, that's expensive. But once you
have that capability, getting a fleet carrier is actually dramatically easier than...pretty much any difficult thing in most other games. It takes hundreds of hours to get a top runeword in Diablo 2, for example. By contrast, I know of players who can earn the money to buy a fleet carrier in approximately 5 hours. There are many players who have not only a single carrier, but multiple carriers on multiple accounts!
So in reality, your chart would look more like this:
And quite likely even closer than that, because a fleet carrier will more often
save you money than cost it. Just jumping your carrier instead of delivering a ship saves you over a week's worth of upkeep. Just storing mined goods instead of selling immediately can earn you hundreds of weeks of upkeep.
I maintain my statement; upkeep is trivial. In fact, I think it's most often
less than trivial.
