Where did Bridgeport's working class and middle class move to during and after WW2? And where did Bridgeport's more prosperous people move to when they, or their kids, moved out of the center?
Of course, they moved to wherever their company moved to - or the suburbs, to the new developments or old houses on farmland in surrounding towns like Hamden, Monroe, Fairfield, Easton, Newtown, Stratford. Also, quite a few moved to the northern, suburban part of Bridgeport. In time, these surrounding towns and areas developed their own economies independent of the city, with office parks, retail, light industry, corporate headquarters, multiplex theaters, churches, and even their own universities (eg Quinnipiac University and Fairfield University).
With this de-urbanization and the simultaneous deindustrialization of the northeast, the city core lost its tax base, its jobs, and its vitality. Crime and drugs became endemic with no-go zones for police. Cars, and government-built highways, made the flight that much easier. In response, the city did what all Blue Cities try to do: they raised taxes, applied for federal Great Society urban funds and programs, and sunk into corruption. Death spiral.
Very few old Connecticut cities escaped that. Stamford, CT for one, barely did escape, but Stamford (pop. 122,000) is really a NYC suburb now. It is alive because of huge tax breaks it offers to giant corporations, mainly banks poached from NY. No breaks for small businesses.
A few pics of houses in a pleasant part of leafy, suburban Fairfield, CT; once a semi-rural suburb of Bridgeport but now it's more economically-attached to NYC despite the 1 1/2 hour commuter train ride.
With wifi and plugs, a train ride doesn't need to be a waste of time.
