Pride and Prejudice
"Indeed, Jane, you ought to believe me. No one who has ever seen you together can doubt his affection. Miss Bingley, I am sure, cannot. She is not such a simpleton. Could she have seen half as much love in Mr. Darcy for herself, she would have ordered her wedding clothes. But the case is this: We are not rich enough or grand enough for them" (21.18)
[Colonel Fitzwilliam:] "[…] But in matters of greater weight, I may suffer from want of money. Younger sons cannot marry where they like."
[Elizabeth:] "Unless where they like women of fortune, which I think they very often do."
"Our habits of expense make us too dependent, and there are not many in my rank of life who can afford to marry without some attention to money."
"Is this," thought Elizabeth, "meant for me?" and she coloured at the idea; but, recovering herself, said in a lively tone, "And pray, what is the usual price of an earl's younger son? Unless the elder brother is very sickly, I suppose you would not ask above fifty thousand pounds." (33.12-15)
"In marrying your nephew, I should not consider myself as quitting that sphere. He is a gentleman; I am a gentleman's daughter; so far we are equal." (56.51)
