The only solution is to consolidate Detroit (and its school district) with all of its contiguous communities under a new government with rational constraints. What does Wayne County include? There is a LOT of prosperity in the area, largely an outgrowth of the new Government Motors and its hundreds of vendors and service providers.
The fortunate suburbanites (fortunate to have been bailed out when they went bankrupt) have intentionally let Detroit go to the dogs, but who would want to live in Grosse Point if it had not been for Detroit's power? Consolidation will be painful, but it is necessary.
