Yes, but at least Philly and Detroit aren't attracting "immigrants," which makes them paradises for many Freepers.
Much as I despise illegal immigration, I still believe that those cities (or neighborhoods) that attract immigrants tend to be in better shape than those that don't. Ferry Street in Newark is filled with restaurants, delis, small stores, etc. run by Brazillians, Ecuadorians, Portuguese and Eastern Europeans. You go to the black areas, all you see are fast food joints and liquor stores.
Detroit is so run down they can't even attract flies to the carcus of the city.
