Detroit is going to collapse under its own weight. Downtown is going to lose more business as the population becomes poorer and poorer until not even a basic grocery store can survive. Businesses continue to close as people shop less and people shop less as businesses offer less jobs.
Eventually downtown becomes deserted with old Going Out of Business signs flapping in the wind from empty and broken windows. Dilapidated buildings become squatter cities, smoke pouring from windows as the homeless burn what they can to stay warm in the Detroit winters. The food supply from abandoned apartments and restaurant dumpsters slowly disappears as it either rots or gets picked through. Things become even more desperate. Violence becomes the norm in the struggle for supplies.
The outer areas start to see an influx of violent homeless people, robbing and stealing to stay alive. Suburbs experience exponential increases in robberies and muggings. The police, tied up with the downtown situation, are spread thin as it is and can’t help the dwindling middle class. More and more leave Detroit, in search of safer, more stable cities.
The homeless spread further and further out as the inner city becomes gang territory where gunshots echo throughout the night and bonfires in the streets dimly reflect off of the broken windows high up in the abandoned office buildings.
Finally, as the last home owners and tenants in the Detroit area pack up their vehicles and leave, the ‘undesirable’ population begins to die out, eventually leaving the biggest ghost town in America.
…At least that’s the best that could happen.
