It won’t happen, but my idea for “fixing” Detroit goes like this:
Make all the people move out. All of them.
Bulldoze all the buildings. All of them.
Sell the land by the acre to anyone with real money.
Build a new city from scratch: No criminal class, no debts, no unions, no pension liabilities, no aging infrastructure, no one in the city who does have real investment in building a workable city.
It’s the equivalent of “taking off and nuking the city from orbit”. It’s the only way to be sure.
There is a reason the bankruptcy court trustee takes the bankrupts’ credit cards away from them.
