Urban planner Pete Saunders, a Detroit native and Chicago resident, doesn't see many similarities between the two cities:
Chicago has a much larger and more diverse economy to draw from to address its debt concerns. A report from the federal Bureau of Economic Analysis released in February shows that Chicago metro area GDP in 2011 was $548 billion annually, making it the third largest in the nation after New York and Los Angeles. That makes the Chicago economy nearly three times larger than Detroit's, which checks in at $199 billion. Chicago's economy is also more diverse than Detroit's, with no one industry sector making up more than 13 percent of the metro area workforce. Chicago's economy also enjoys demonstrated strengths in areas where Detroit is weaker — specifically, finance, transportation and warehousing, and education. There is simply a broader and deeper reservoir that Chicago can tap.
Perhaps more important, there are key historical differences that led Detroit to bankruptcy but kept Chicago on a growth path. Circa 1950, Chicago and Detroit were mid-century manufacturing doppelgangers — economic powerhouses teeming with industrial businesses, each with a bevy of skilled and unskilled workers to employ. However, governance differences caused their paths to diverge. Mayor Richard J. Daley is often remembered as the quintessential machine politician, but he cut his political teeth in fiscal policy before occupying the fifth floor at City Hall. He put that expertise to good use while in office. Also, the dozens of municipal corporations and special-purpose districts here, lacking in Detroit, meant the fiscal burden could be spread around. As a result, City Hall ends up having fewer direct responsibilities and a slightly rosier fiscal picture.
When Detroit doubled down on flinging its population into the suburbs in the last half of the 20th century, Chicago cleaned up. I remember the smog, dirt, and crime of the 1980s vividly—and the stunning clean-up in the 1990s. During the same time, Detroit emptied out even more.
Detroit shows just about ever method available for killing a city; Chicago shows the opposite. Urbs in horto is a reality.
