So why has Detroit suffered unlike any other major city? Planning, or the lack thereof for more than a century, is why Detroit stands out. While cities like Chicago, Philadelphia and Los Angeles (don’t laugh – Detroit and LA essentially boomed at the same time) put a premium on creating pleasant built environments for their residents, Detroit was unique in putting all its eggs in the corporate caretaker basket. Once the auto industry became established in Detroit, political and business leaders abdicated their responsibility on sound urban planning and design, and elected to let the booming economy do the work for them.
