what does Scrooge learn from the Christmas present ghost

Scrooge learns about all the misery that is around him. Scrooge sees under the robe of the Ghost of Christmas Present, two children, whose names show that they are symbols: Ignorance and want. They are your standard impoverished Dickensian children; they are ragged in clothes, dirty and starving. Scrooge begins to understand the error of his miserly ways.
