&gt; Have these jobs existed in the US in the first place? Was it commonplace for people to have cooks for example?<p>IIRC, yes, there was a time (up through the late 19th, early 20th century) where having at least one live-in household servant, often either specifically a cook or a generalist where cook would be part of their duties, was typical of the middle class, and not entirely uncommon in the middle class through the middle or so of the 20th Century.
