Thanks for posting that! It was a very interesting and somewhat depressing read. One thing I remember very clearly from my first visit to a Disney park (Disneyland) in 1992 when I was but a young boy was all the interesting little shops on Main Street USA, in NOS, etc that, I guess, were already on their way out by then. My first visit to WDW was in 1994 and I remember it didn't seem that they put as much thought into their retail locations, outside of perhaps World Showcase.
The obvious thing that strikes me upon reading that article is how watered down the theming has becoming in the parks. All the talk of retail and dining being designed to tell a story has more or less been thrown out the window beyond a few holdouts such as WS and AK.
Another thing is that I can't imagine people buying stuff like inlaid pearl brassware and eastern silks in a theme park. I'd be interested to know if these shops ever really moved much merchandise or whether the purchasing habits of visitors changed significantly from 1971 to the 1990s. I suspect, more than anything, the change to mass-market branded merchandise reflects the need for corporations to ring more and ever greater profits out of everything beginning sometime around the 1980s that goes far beyond Disney. It is possible Disney was happy with the shops bringing in modest profits with the notion that they were part of a larger whole. I can't imagine any middle-manager today being able to justify low profit margins at stores on the basis they reinforced the show.
Either way, it is sad to see all those images as the shops and their merchandise really do evoke different places very effectively. Nowdays, themed retail in MK means Moana plush alongside the Frozen dresses in Adventureland.
