Male v female characters in Middlemarch

Trouble brewing on two burners in George Eliot's MIddlemarch: Fred Vincy has started working for his prospective father in law, Garth (Mary's father), and it's obvious that he's completely incompetent at office work and that Garth sr. will have to put up with a lot if he's ever to train Vincy to participate in let alone take over the business; moreover, Fred V. is now realizing - only because Mrs.Garth has told him directly - that his courting of Mary has put off another more suitable partner, Rev. Farebrother: a much more stable, less selfish, more mature man. Will Fred step aside, or will he step up? Meanwhile, the Lydgate family in deeper trouble: Dr. Lydgate, married to Rosamond Vincy (Fred's sister) has gotten into serious debt - his income has fallen (in part because of his arrogance and his opposition, justified but still, to all of the other Middlemarch doctors) and he's tried to live way above his means, in part because of the habits of his own well-to-do upbringing and in part to satisfy the Rosamond's tastes: Rosamond is a social snob, pure and simple; she knows she's the best-looking woman in the room, and she does just about anything to charm Lydgate's cousin, Captain Lydgate, a "baronet," more of the noxious and pervasive British class structure. Eliot is pretty doctrinaire in creation of her female lead characters - they're either all good (socially committed, Dorothea and Mary) or narcissistic and naive (Rosamond, Celia); the male characters are more nuanced I think - but Dorothea, as the central character when all is said and done - will learn and grow and suffer in pursuit of her noble ideals.
