How does Dickens presents Scrooge's changing attitudes in Stave 2?

In Stave II, the Ghost provokes Scrooge's redemption from miser to a good, charitable Christian. He has two strategies: he reminds Scrooge of his own loneliness, and gives Scrooge models of intimacy to which he should aspire. Scrooge gains empathy for the neglected (and, implicitly, the poor, who are otherwise neglected by the rich) when the Ghost reminds Scrooge of his own neglected childhood, inspiring him to want to give to the caroling boy he neglected.

On the other hand, Fezziwig is the paragon of friendship, and his scene makes Scrooge reflect on his own callous treatment of his employees. Finally, the Ghost shows Scrooge how money has interfered with his potential romance and the joys of family life. All of these scenes expose how money has driven a wedge between Scrooge and others, and his loneliness, which he seems to have repressed for years, is returning in profound new ways.
