I was one of those people hand retouching photos for a living.
I was a Photolithographer, and oh how we laughed at those bumblers with their tiny little computers, taking hours to do what we could do in minutes.
Of course that changed fairly quickly, and we all wound up in front of a monitor.
Then the boss realized that if he advertised for "Graphic Designers" he could get kids straight out of school desperate to be hipsters at minimum wage, and that was that as far as a career went.
The kids were usually clueless, but as the job had degenerated into putting pictures into boxes, not many clues were needed by that stage.
