This is my first topic starter experience I'm sorry if this topic is redundant I tried to find one similar but couldn't.

So as I was watching Movie 1(I'm on episode 153 but afraid of diving into the next arc decided to watch a few movies instead), and I started to think.

Where does the rest of the crew get cash? I know Nami gets a bit of treasure from time to time but the treasure that the crew gets always seems to be hers. But then if she pays for another crew member she always mentions interest. Yet, where the heck does the rest of the crew earn a living to pay her back let alone interest? Is it all just a front so that people don't realize how generous she is and in fact she is paying for all the crews expenses? I just can't recall a time anyone other than Nami earned a single Belli.
