I am not giving money to the people that can not get money for themselves.
Scrooge loves money and thinks it gives him power so money is a symbol for him.
Scrooge is a selfish and dose not care about his family. For example ,"Love? That's the only thing in this world more ridiculous than Christmas. Now, good day, Nephew!" This shows he is being selfish to his family, because he's yelling at his Nephew.
