A few decades ago (about 1978) I picked up my neighbor (he was in his eighties) and took him to a car show with me. Though there were five decades separating us we had a lot in common and attending car shows was one of them.
We took in the show and went to an ice cream emporium for a cool refreshing snack. Looking at the price list he commented that when he was a student working part time in a soda fountain a banana split was thirty five cents, now they were three dollars. I asked what year he was working in the soda fountain, he said 1939. Asked what his wages were he said thirty cents an hour. At that time (1978) the minimum wage was two dollars and sixty five cents so I told him the price was the same as it had been when he was a kid; a bit more than an hour's pay at minimum wage.
