Living without electricity was common within living memory in rural areas. My still-living mother had no electricity on the farm until she married.
My still-living father did grow up with electricity for their light bulb (singular) and radio. They were urban. Granddad was in construction and carpentry, or most any job with a paycheck in the Great Depression.
Until five years ago a neighbor six doors down the block had no electricity because it was too expensive to be worth it. It was startling for newcomers to see smoke coming from the chimney in August in Texas at dinnertime. I'm not sure what job she had before retiring.
I'm not sure how I'd tell if a co-worker did without electricity at home.
