Manufacturing jobs may have become less in numbers but they are no way near gone. So i’m not sure that really counts as a valid answer.

Same with mechanics. These jobs are not gone but possibly shrunk in total # of jobs. Quality may have gone up but so has complexity of repairs.

Now, farmers. Again, these jobs may have shrunk but the jobs are still there. I could count on both hands of families I know living in proximity to me that run family farms for business. You can drive 30 miles from me and go through three towns that are maintained because of farm land.

edit: on mobile so didn’t see your decline != elimination note at first
