There is something to the mentality of the people who settled a place being an important factor. For years the book Seeds of Albion was considered authoritative about the "folkways" of the United States which broadly implies that snooty but moral NE settlers around the Plymouth Rock settlement were different than cash crop-loving (and eventual slave-holding) Jamestown settlers who were different from fringe British Caledonian and Celtic martial types who settled in the Allegheny and Appalachian mountains, never mind the criminals who settled in Georgia. Fine as it goes but any analysis that ignores the Dutch culture in West Michigan, the Scandinavian and Finnish culture in the upper Great Lakes not to mention the Polish and Italian culture of the cities.
It still means a lot that there are variances in place. The character of Hamtramck is definitely shifting but is that bad? Its bad if someone says its bad. Chinatowns were a thing in most cities and now they have to be historical theme parks to protect that character with funding. Its like keeping Tiger Stadium up as a monument. Its fine but does it actually serve a public good to do that. Invest in the good and mitigate the actual bad (crime, excessive vice) vs change as bad (they look different, they eat different food).
