I don't really agree with this authors analysis of Austen. Like on Pride and Prejudice, "Elizabeth Bennet wants to marry for love and respect, but in her world marriage is fundamentally about economic security and social alliance." Elizabeth grew up with her parents fairly disastrous marriage (where her Dad doesn't respect her Mom) and inability to think in the future which put the girls in such a bad situation (her father should have saved money up instead of just assuming he'd have a son eventually). She is reacting against that, wanting a husband that will have mutual respect AND the economic security of someone who is responsible. She wouldn't just want to marry someone for love who wasn't able to provide her economic security, just like she doesn't want to marry Darcy she doesn't respect him. This article makes it sound like she is rejecting the social expectations of her society, but only her mom really wants her to marry Mr. Collins and as seen by her own marriage and support of Lydia's marriage she is a pretty bad judge of what's going to make a good life.

Later they say "They also both, mostly, focus on characters who have enough privilege to have choices, but not enough power to escape circumstances. Characters in both aren’t peasants without agency, but they’re also caught in larger systems they can’t opt out of" But that just describes basically everyone, none of us have no agency, but all of us are also caught up in larger systems we can't opt out of. But even within Austen you have Emma, who is entirely economically and socially secure and doesn't need to worry about anything and Fanny who lives entirely at the whims of others.
