I live close to an area where, in a previous "gilded age", business magnates acquired large tracts upon which they established estates. Over the subsequent decades, many of those were sold off and turned into -- often quite nice -- housing... well, "tracts", doesn't really fit. Nor does "sub-division"; the use of that word came later and also does not connote the upper scale nature many of these areas. (Hey, as I suddenly recall, my home is more modest and is not located in the heart of the area I'm thinking of, but I live on what was formerly a substantial country estate of one of these magnates.) Anyway, my point is, the trend for several decades has been that old estates have been broken up into smaller units. Sometimes, a smaller "core" of the estate remains as an actual estate, perhaps even in the original family, but land-wise, people have "downscaled". Now... We in the U.S. appear to on the verge of having a new round of estate creation. Gilded age, indeed.
