Blame the right for a town run by the left. Might as well say it was bush's fault.
So you freely admit that the Right has nobody living in Detroit, and couldn't pronounce Gratiot without a detailed instruction manual written by an Obama-loving Socialist, but you're nonetheless claiming they know why Detroit isn't working? Neither national side knows enough about Detroit to fix the problem.
The basic problem is that the current boxes on the map called Detroit is an incredibly dumb idea. It's per capita income is barely five figures ($12k or less), in a region where per capita income is actually pretty high ($49k). Which means that if local government costs are $700, the other cities have to scrounge up 1.5% of local income, but Detroit has to find almost 6%. The only way to make that math work is a) fire the police department and hope the criminals don't kill everyone before enough rich anti-tax activists move in to solve the per capita income problem; or b) tax rates have to be four times as high. Since a) is obviously unworkable, Coleman Young tries b) when he got the state to approve municipal income taxes. But he couldn't get the full 4 times, so he settled for slightly less then double. Which kinda worked, but also meant taxes were double the neighbors and we still didn't have enough money to deal with crime (the crack epidemic did not help).
Over the long term that meant that the only businessmen who stayed in the City were criminals (they'd be morons to move to some place that actually had the budget to arrest them; everyone else OTOH...), which means your number of capitas goes down but the total cost of policing stays the same. But there's another huge problem if your population is shrinking: 1.5 million could probably support the pension costs for a city that peaked at 2.5 million or so in the mid-50s, but 700k sure as hell can't. Which means the number you now need is more like $1,500...
So Orr could have done a couple things. He could've tried to get state law changed so Detroit could jack-up taxes more, but he was appointed by an anti-tax Republican. The option he took was to get those pensions, and several other major obligations, cut down in bankruptcy. Either taxes or bankruptcy would probably work for a few decades before the money ran out again. Given the resurgence of Detroit's Midtown area, and the continued exodus of the working class (who are expensive to govern and not very lucrative to tax), it's theoretically possible the few decades will be enough.
The way to definitively solve the problem would have been eliminate all of the little Cities in Michigan that make up Metro Detroit. But there's two much racial BS for the local whites to not make that a huge hassle, and said local whites are quite politically connected to both sides nationally.
Thus you have everyone, on both sides, trying to shoe-horn national issues into a very local debate.
