pride and prejudice:jane austen description

Mr. Bennet of the Longbourn estate has five daughters, but his property is entailed, meaning that none of the girls can inherit it. Since his wife had no fortune, it is imperative that one of the girls marries well in order to support the others on his death. However, Jane Austen's opening line, “It is a truth universally acknowledged that a single man in possession of a good fortune must be in want of a wife.” is a sentence filled with irony and playfulness. The novel revolves around the necessity of marrying for love, not simply for monetary reasons, despite the social pressures to make a good (i.e. wealthy) match.

****CHAPTER1*******
It is a truth universally acknowledged, that a single man in possession of a good fortune, must be in want of a wife.
However little known the feelings or views of such a man may be on his first entering a neighborhood, this truth is so well fixed in the minds of the surrounding families, that he is considered as the rightful property of some one or other of their daughters.
"My dear Mr. Bennet," said his lady to him one day, "have you heard that Netherfield Park is let at last?"
Mr. Bennet replied that he had not.
"But it is," returned she; "for Mrs. Long has just been here, and she told me all about it."
Mr. Bennet made no answer.
"Do not you want to know who has taken it?" cried his wife impatiently. "You want to tell me, and I have no objection to hearing it."
