I Don't Think....
....That non-collectors "get" the economics of collecting at all.
I remember years ago, when my mom passed on her Lady Kenmore 30-inch smooth-top to me. The range was an expensive one, but it had for several years been the recipient of Mom's Special Care Program, which alternated extreme neglect with outright abuse. For that reason, the control panel glass was in bad shape, with some delamination of the paint on its back side. I decided to replace it and made the necessary trip to Sears Service, which in those days had parts in stock.
When I was through with the needed spa treatment, Mom was the first to admit that the range was looking spiffy again, but then she asked what the replacement glass had cost. I told her - around $40. She said, "You're crazy to spend that on a piece of glass! Throwing money around!"
I did not have the heart - or the cojones - to remind her that she'd paid over $400 for the range and had gotten something like three years out of it before deciding to replace it, not least because it was looking pretty scabrous.
