For a working-class and middle class city, by the turn of the century central Bridgeport boasted large neighborhoods consisting of the McMansions of the time. Real in-town mansions on once-Elm-lined boulevards.
Also, large neighborhoods of less grand but entirely spacious and respectable upper-middle class homes with 5-6 bedrooms, usually a sleeping porch upstairs, servants quarters on the third floor, and rooms off or above the barn-garage for a driver, whether of carriage or of automobile. The economy was booming, new Irish and Italian immigrants were eager for factory work or domestic work - and there was no income tax. (Here's a bird's-eye view of one such neighborhood only blocks from downtown.)
Instead of government spreading the wealth around, people spread their wealth around in their own ways. Even the then-ubiquitous trolley lines were privately-owned.
Here are a couple of Bridgeport mansions. These survivors are in the South End. There is essentially no market for either category of the old big homes which, if situated elsewhere in Fairfield County, would fetch millions.
