In some places - Detroit is an example - people start leaving, the tax base dwindles, and by the time they realize the need to demolish things, the funds aren't there. In some cases, the city pulls in its borders and declares the former-city areas someone else's problem.
Here's a Detroit residential neighborhood suffering it now: https://www.msn.com/en-us/news/us/eerie-images-of-detroits-m...
I don't think that's a totally unfair statement depending on the region though. At least in Seattle a fair amount of homes are Craftsman homes which haven't aged well since they were ordered directly from a Sears catalog without considering the very wet local climate of the Northwest. (And yes, that Sears and that Craftsman.)
I'm aware of Sears catalog homes but not of any link between the Sears owned Craftsman tool brand and the craftsman style of home, which is connected to the Arts and Crafts design movement. Can you provide a reference?
I do wonder if the tool name (apparently a brand purchased from a small Chicago toolmaker by Sears in 1927) was inspired in part by the architectural movement, which was the product of a specific designer (Gustav Stickley) in the early 1900s.
I couldn't find any references to such a connection though.
