On the Rich Doing Their Own Laundry

Brad DeLong recently quoted the following snippet from an email he received on his blog:

In Agatha Christie’s autobiography, she mentioned how she never thought she would ever be wealthy enough to own a car – nor so poor that she wouldn’t have servants…

Today, having servants is a luxury only open to the rich, whereas owning at least one car is a standard part of middle class life, outside of a few major cities.

Automobiles were the luxury, whereas most middle class families could afford live in servants (the same is true of many developing countries today).
