This is a pack of gum as it might have appeared in 1944. It cost about 10 cents.
This is today’s chewing gum packaging. It now costs $1.39 for about the same amount of gum.
The price has gone up 14X.
This photo shows the baked bean packaging design and technology of 1944 next to that of today.
Not much difference, eh? The price appreciation since 1944 has only been 7X, half that of chewing gum.
Not a terribly scientific study, I know. Just thinking.
