These are the most difficult days for Cities in America, ever. Daily, we see the symptoms of their struggle with crime, the homeless, and the drug-addled on their squalid sidewalks. The internet is full of videos of the "trank" addicted in Philadelphia, the muggings and fights on New York Subways, and the "Shooting galleries" in San Francisco. It's not a pretty picture. Most of us, myself included, are overwhelmed by the human degradation of these suffering people.
