How would you describe the relationships between these characters: Walter, Ruth, Travis, Beneatha, Mama within their family structure?

Each of the members of the Younger family has various
aspects of their personality that make them an essential part of this play.  Walter Lee
seems to feel as if he is forced into a mediocre job as a chauffeur when there are
bigger and better things that he should be doing.  One of the characters that he feels
has forced him to live this life is his sister, Beneatha.  He feels that because she is
going to college and he is forced to provide for the family and help pay for her
education, that she is taking away from his opportunity to go further in life.  Beneatha
does not understand this at all; she is a character that believes that, as a woman, she
should be able to get this opportunity and that Walter should be happy doing what he is
doing.  This is a bit contradictory because she sees Walter as someone who should be
complacent but she will never be happy with being just an “ordinary” person.  Ruth seems
to be content with their life even though she knows that she would someday like to give
her son a better life.  More than anything in the world, Mama wants to show her children
that just because they are African-American, it does not mean that they should be forced
to “settle” with anything.  This is why she takes her money and puts a deposit on a
house in a “white” neighborhood.  She does not care how her new neighbors will look at
her; her main concern is with her own family and making a good life for her children and
grandchildren.
