Do you know of anyone who argued both that the lower classes should be kept busier and that inherited wealth was bad because it discouraged industriousness?
Adam Smith, one of the quoted people, said that gentry practice of dividing their estates was good because make them work just to return to the wealth they had grown up with. Actually, I think his point was less about effort than about overcoming risk aversion.
Dalrock writes an interesting article related to Dr. Helen Smith's book the Marriage Strike. I really have to bump it up on my too rapidly growing reading list. (^_^)
