Semi-related anecdotes: After the Civil War, when many plantation properties became economically unsustainable, occasionally the main house would be abandoned by the owners, and the remaining sharecroppers would take up residence; one house that used to be for one extravagantly wealthy family, now occupied by a handful. In Newport, RI, after the income tax made maintaining grand Gilded Age domiciles untenable, many were subdivided into multiple units. Again, a house for one family (and there servants) turned out to be decent housing for multiple. People keep saying that America has a building deficit, and to some extent, we do. But we also have a lot of physically massive houses that house one family, because those families can currently afford it. Historically, that has not been a permanent state.
