What happens now?

So what now? The play has ended and the characters have moved on, but is the story really over? At the end of A Raisin in The Sun Walter finally proves himself to be a man, and despite the lack of money, he decides to move his family into their new house. The play ended on a happy note leaving the Youngers full of hope and optimism that can be felt by the audience, but honestly how practical was their decision? After six generations the Youngers were finally given the chance to move into their own place and have a house that belongs to only them. This was a momentous occasion that can easily be marred by their current financial issues along with the neighbors in their new community. The way the play ends gives the audience a sense that the Youngers will be fine and live happily in their house, but what if this is not the case? Even with four working adults to compensate for their impoverishment, the Youngers still have to deal with the fact that they are a black family living among a community of whites who do not wish for them to be there. The ending of A Raisin in The Sun is heartwarming and uplifting, but is it all a facade hiding the harsh reality of life? 

Does anyone else feel that what happens to the Youngers after the play might not live up to the suggested happy ending?
