There are certainly a number of different characters you could choose to examine in this great play, however, for me, one of the characters that most clearly represents a dynamic character, is Walter. When we first meet Walter, we are presented with a man who is consumed by dreams of having a better life. He desires to invest the money from his father's insurance in a liquor store and to make money by his own efforts. He constantly refers to his idea and how money can be made through starting a business:
Charlie Atkins was just a "good for nothing loudmouth" too, wasn't he! When he wanted me to go in the dry-cleaning business with him. And now- he's grossing a hundred thousand a year. A hundred thousand dollars a year! You still call him a loudmouth!
He is therefore a man obsessed by the tantalising prospect of the "easy win," a way of making money on his own terms that will bring him and his family prosperity. However, when his mother gives him a chance to do exactly what he wants to do, it ends in tragedy, as his partner runs away with the money. However, although he appears defeated, deflated and hopeless, it is precisely at this point that he has a chance to assert himself as an adult and leader of the family, for he is able to resist the temptation to give in to Karl Linder and rejects the cash offer for his family not to move into the neighbourhood where their new house is:
And we have decided to move into our house because my father - my father - he earned it for us brick by brick. We don't want to make no trouble for nobody or fight no causes, and we will try to be good neighbours. And that's all we got to say about that.
By making this choice on behalf of his family, Walter shows his maturity from an adult who always hankers after impossible dreams to a man who is willing to take responsibility for his actions and decisions in life, proving him to be a dynamic character.
