My parents-in-law started their careers as management consultants. The job in their time was much higher prestige and much higher value than it was when I started my career; free flow of information over the internet and commodification of spreadsheets changed all of it. From my parents' generation, I know practical effects folks who became unemployable once movies went to digital effects; engineers who found their draftsmanship skills obsolete. Folks with near-photographic memories whose entire superpower was destroyed by computing. I personally grew up in a blue collar community that was income depressed because its labor became commodified, though that was due to mechanization.
