Excellent topic, zoot. Thank you also to Hadilly for the New Yorker article. Post 24.
Cerat01an raises the custom of entailed estates, to stop profligate sons squandering the capital. On the other hand, the ancestors of Mr Darcy and Mr Bigley were able to buy land from nobles, so that Mr Darcy and Mr Bingley were gentlemen, but not nobles. The gentry class in old England was confident, as was the gentry class in old China.
Jane Austen is said to have remarked that 'she wrote about love and money, because what else is there to write about?' I cannot vouch for the quote, but it is in character.
Supporters of Jane Austen are known as Janeites.
I think Jane accepted the world as it was. She may have privately held some feminist views, but in her day, agitating for change would have got nowhere.
