There's an idiotic news story out there about how JP Morgan is investing 100 million dollars in Detroit over a period of five years. This is being portrayed as a good thing, but it's actually quite pitiful. 20 million bucks a year doesn't buy very much, even in a depressed region. It could provided financing for a hundred new homes, or a thousand automobiles, or maybe ten crappy fast food franchises.
I do not know what type of investment would "save" Detroit, but JP Morgan is signalling that the city is not worth very much.
