The instinct to preserve and honor Frank Lloyd Wright in Oak Park, where I live, has basically frozen the place in amber, which isn't something Wright would have wanted, and also worked synergistically with exclusive zoning to keep the Village ultra-expensive (it directly abuts the Austin neighborhood in Chicago, which is low-middle income) and white (unlike Austin, which is 90+% Black).
No idea what Wright would have thought about racial housing segregation, but it was certainly a knock-on effect of the preservationist cult he accidentally created.
