Exploiting?

From an old favorite:

"Exploiting?" asked Dirk. "Well, I suppose it would be if anybody ever paid me, but I do assure you, my dear Richard, that there never seems to be the remotest danger of that. I live in what are known as hopes. I hope for fascinating remunerative cases, my secretary hopes that I will pay her, her landlord hopes that she will produce some rent, the Electricity Board hopes that he will settle their bill, and so on. I find it a wonderfully optimistic way of life."
