How does walter younger develop throughout the story?

In "A Raisin in the Sun," we meet Walter Younger. Walter is often mean to other characters, picking fights with his sister Beneatha, being rude to his wife Ruth and impatient with his mother Lena. This is because Walter is very unhappy with his life. He hates working for a white person and cannot see a way to improve his situation. He also feels guilty about not being able to provide for his family.

When the money arrives, Walter is excited about using the money to invest in his business idea. When Walter's mother uses the money for a down payment on a house, Walter goes on a three-drinking binge and refuses to work. His family agrees to give him some of the money, which he ends up losing. He is later on tempted to compromise his dignity by accepting the money that Mr. Lindner offers them.

Walter is portrayed as a man who is deeply unhappy with his life, but is not beyond redemption. He can have moments of kindness and warmth. The author implies that his character is so affected by the circumstances of poverty and racism in which he finds himself. However, towards the end of the story, Walter undergoes an enormous transformation and is able to regain confidence and self-respect.
