Why does Scrooge not care for the poor?

At the beginning of the story he believes that they should just go to workhouses, prisons, or just let them die on the street. He feels that if those unionhouses are still working, why should he give up his own money?

But in the end of the book once he has been visited by all of the three spirits, he goes back up to the men who were working for that same charity, and gives them a large donation.

Hope this helped! :) I just read the book so, ya
