serveimage-2I just came across an advertisement from JP Morgan Chase in the Atlantic. “What the rebuilding of Detroit can teach us” was the tag line. What caught my eye was the accompanying photograph of a downtown scene with a futuristic-looking streetcar rolling down the street. It looked like one of those hi-tech jobs one sees in German or Swiss cities. A closer look at the small type revealed that this was a “rendering,” what used to be called an “artist’s conception,” before PhotoShop made such images entirely lifelike. The so-called M1 line is currently under construction; it will run all of 3.3 miles. At least that’s longer than the often-ridiculed People Mover, the elevated and automated train that circulates downtown, largely empty. The flood of comeback stories about troubled Detroit reminds me of the reporting about New Orleans after Katrina. Both follow a formula: first the bad news, then the good news—rebuilding, recovery, renaissance. We’ve been there before: Detroit’s Renaissance Center dates from 1977.
