The point of discussion between Joe and Mrs. Dilber is whether it's correct to steal things from Scrooge's house after he's dead.
We can arrive at this answer because:
Scrooge is a very rich man, but he is not friendly and loved by anyone.
People have no respect or attachment for him and for anything he does.
That's because he withdrew from everyone, didn't live a community life, and didn't cultivate friendships.
Scrooge is privileged to see his future and finds he's dead, no one misses him, and Joe and Mrs. Dilber are wondering if it's correct to steal the objects from his house.
