When they retire, some parents like to move to more rural and out of the way areas. It can be really difficult, sometimes impossible to find a well enough paying job in the middle of nowhere.
Happened to me; work in the tech sector in engineering as a tech and will be continuing classes for ME and/or EE. No way in hell would I find a job where they live that makes use of my experience. (I’d likely have to start anew by flipping burgers or be a slave at Amazon)
