I visited the Biltmore Estate years ago, the home of the Vanderbilt family. It occurred to me during the tour that all the end result of all this wealth was approximately equivalent to having a 5 bedroom McMansion. A huge percentage of the sprawling property was dedicated to housing servants who performed tasks like laundry, changing the water in the (pre-chlorine) pool, taking care of the horses and carriages of visitors, or preparing meals that today are mostly completely automated or unnecessary. The end result was housing the owners and a few guests in conditions substantially worse than the average modern suburban home.
