It was definitely fairly common for middle class in my neighborhood (60&#x27;s, 70&#x27;s US) to have a cook or a maid, at least for special occasions or maybe a few times a week.<p>We also had diaper service, dry cleaner, milk, and Charles Chips: all pickup and delivery by a dedicated truck on a regular schedule.<p>All these service jobs are gone now. Dead tree newspaper delivery is next.
