After all the various twists and turns, the numerous setbacks and misunderstandings, the conclusion to the story is generally a happy one. Jane and Elizabeth fulfill society's expectations by getting married to eligible men in possession of a good fortune. For a while, this seemed impossible. Darcy was always too full of pride, regarding Elizabeth as his social inferior. For her part, Lizzie was unable to overcome her prejudice toward Darcy, who appeared to be a such a cold, aloof figure. Thankfully, they've both managed to overcome the barriers between them, and now they're set for a life of wedded bliss.
It's a similarly happy outcome for Jane. She weds Mr. Bingley despite Darcy's earlier efforts to derail their relationship. Once the little misunderstanding between Lizzie and Darcy was cleared up, the route was left open once more for Jane to pursue the man of her dreams. All in all, this is the best possible outcome for Mr. and Mrs. Bennet, as two of their daughters have been married off to rich, eligible men, and that's what they wanted all along.
The only real fly in the ointment is the Lydia situation. Although she too has been married off, it soon becomes painfully obvious that her feelings for Mr. Wickham are not fully reciprocated. To make matters worse, her marriage to Wickham entails constantly moving from place to place, leaving behind a trail of angry creditors in their wake.
