Dickens uses description of three characters - Scrooge, Fezziwig, and the Ghost of Christmas Present - to show different Victorian attitudes towards the poor. Scrooge embodies the selfish rich and ignores the poor, while Fezziwig generously cares for his employees' well-being. The Ghost teaches Scrooge compassion and the importance of addressing social ills like ignorance and poverty. Through these characters, Dickens conveys his view that the Christmas spirit of goodwill and charity should last throughout the year.
