Well, it's not to her face, of course, except veiled (and Mrs. Bennet never understands anything veiled). I suppose it's more implied than anything that part of their reason for despising her is because of her obsessive concern over getting her daughters married. I don't want to say that Mrs. Bennet is not vulgar or rude or selfish or any of those other things, or that Lady Catherine and Caroline, etc, are wicked. But I think that it's valid enough to say that Caroline, for instance, blames Mrs. Bennet for trying to get Jane married to Bingley, basically because she considers their family far above them, even as she, Caroline, is aspiring to a match with a man at least that far above her, and probably more.
I don't really think we have enough information to say what Lady Catherine's feelings were for her daughter, or whether she acted out of concern for her or merely concern for her own sense of self-consequence. I do think she's as rude and vulgar as Mrs. Bennet in her own way, just as likely to speak her own opinion out loud regardless of how it affects the people around her. Certainly the only reasons she gives Elizabeth for why Anne and Darcy ought to marry have to do with rank and wealth. And I think you have to say that she has less excuse for it than Mrs. Bennet. Mrs. Bennet never had much natural intelligence, and no one helped her by providing a good education or teaching her the right way to view the world and act. She's not well bred, but that's not her fault--it's the result of her birth and upbringing, and her marriage to a man who didn't care enough to correct or inform her. (Other, more serious failings, are her fault.) Lady Catherine has intelligence, and a better education and better breeding. She can't plead ignorance or lack of ability. She's just the way she is because that's how she wants to be.
