There's that saying about rats leaving a sinking ship - does that say more about the ship or about the rats?
I mean, does it mean that the metaphorical "ship" is going down or that the people leaving it are rats?
It is only saying that people are leaving the methaphorical ship, not that they are rats.
I think it can be meant both ways. Rats are uninvited, they do no work for what they take, and the moment the party's over, they run off.
OTOH,
everyone leaves a sinking ship, except the captain, who traditionally 'goes down with it'.
So that's my question- are captains really supposed to go down with their ship?
