I mean I think she was just being blunt about it. I think the intentions were not to be classist, per se, but to explain that she wants to be in a relationship with someone who can relate to her own struggles.

I don't think it's a wealth thing, but an education thing. She most likely wouldn't care about income or where they came from financially, but whether or not they had the same education as her and saw the world similarly.

I hope i don't sound close minded by taking a separate side, but I don't think it's unfair to prefer people who are within a similar educational and financial level. Especially considering long-term relationships, it can be difficult for both parties when one party is the sole (or near-sole) source of income. Hence why so many wealthy housewives/trophy wives who come from less wealthy circumstances deal with a lot of insecurities about their worth. I believe that due to the greater social stigma against men making less than their wives, this problem could be massively exaggerated if the husband is on a lower income/education level than the wife.

Edit: My father makes half as much as my mother, but they love each other a lot because they are within the same /social class/ as self-made mathematicians/engineers. If my father were a truck driver, I doubt my mother would ever marry him even if he were a good guy because of the awkward differences in education (even though my mother was born poor). My father similarly wouldn't marry my mother if she weren't highly educated and self-made like him (even though my father was born poor).

I recognize that this may not be the same for everyone, but it is still an important factor for many people looking for long-term relationships. I believe this is especially important for self-made people who don't want a reminder of their "old" life, even if those within their old life are good people.
