Is Black lagoon Company and their members rich?

They regularly accept orders worth tens of thousands of dollars and are paid the same amount for their transportation, protection, etc. But we do not see this profit in practice or in their gear.

Now I know that things like fuel for Dutch's torpedo boat is a huge financial burden, but it can't be that much, no? And yet, both Revy and Rock lives in rather small apartments (when it comes to Rock It's not even that, he lives in hotel and I agree that Revy don't even care if she lives in a nice house or something + can imagine she spend a lot of time in Rock's place) and it also seems that Benny lives on the ship. We don't know what conditions Dutch lives in, although I can imagine it would be a smaller room.

Where does all that money go? Black lagoon Company is probably most famous group of smugglers in all of Roanapur, they should have so much money that they would light cigarettes with dollars....
