Since reading an article about urban blight in Detroit, I've become quite interested in it. I checked the guy's address, and I can see his problem. He says he lives where he does because his girlfriend inherited the house. Normally, one would sell up and move rather than endure a journey like that every day. However, he lives in a blighted area. Their house will never sell.
I've spent some time browsing Google Streetview round there, and looked in detail at some of the properties. You'll see a house occupied and looking normal one year, then the next time-stamp it has a for-sale sign, then the next the sign is gone and it's looking derelict, then the next it's burned-out as a result of arson, then finally the county has demolished it and the site is joining the spreading urban prairie.
The only way to keep a house intact and habitable there is to live in it. And to go on doing that even while your neighbours are moving out and their properties are going down the spiral to the prairie. Your chances of selling are zero. And without a house to sell, I don't imagine there's any way this man would be able to secure any sort of accommodation near where he works. If he can't afford to run a car, how would he afford rent?
The population density goes down and down, and the services disappear. Shops close because there aren't enough customers remaining. The city was built for the car, and if you don't have one of these, you're screwed. I don't know what the answer is, since you can't simply relocate the remaining people into geographically rational population centres and return the rest to farmland.
The empty plots and empty blocks even close to Detroit city centre are jawdropping. Further out, some areas are very nice, but others are grass and fields with a grid pattern of roads and pavements and street lights and fire hydrants, peppered by the occasional house - often two or three houses surviving cheek by jowl as the original plots were narrow and the houses closely built.
It's a whole other world, and I became quite fascinated by it. This little vignette of its effect on one man's life makes it even more fascinating. I'm so glad to hear people are chipping in, and I'll go and donate myself. For the warm fuzzy feeling of actually interacting with something I've only seen courtesy of Streetview.
