What do the Youngers decide to do at the end of A Raisin in the Sun and why?

It is hard not to be moved by the ending of this superb
play as Walter finally turns into the man that he has wanted the opportunity to be
throughout the play and faces down Lindner and the group of residents that do not want
them to move into their community because of the colour of their skin. Even though he
has just lost so much money through his unwise investment and trusting somebody that
turned out to be untrustworthy, Walter still finds it within himself to reject the offer
that Lindner makes to persuade them to stay away from his neighbourhood, and is able to
reject it in a way that bestows dignity and honour among himself. He talks about how
Walter represents the sixth generation of Youngers in the United States and how his
father had worked so hard before finally rejecting the
offer:

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. We don't want your
money.

Thus at the end of the
play the Younger family decide to move into the house that Mama bought with her
husband's insurance payout and reject the offer from the community. They seem to have
recognised a dignity and a pride within themselves that makes them realise they deserve
the same opportunities as whites.
