Don't get getting a city revitalized with a city that's actually growing mixed up, two very different things. Because Michigan as a whole is losing population I live in Flint I should know
I would focus all funds on industrial building revitalization. Also, can Detroit attract all the world's automotive manufacturers to build automobiles? Toyota? Mitsubishi? Mazda? Audi? Porsche? Lamborghini? Then, the middle class and upper middle class will move back to Detroit. Good luck!!
