Not likely. They need the suburbs and the rest of the state to help fund their ongoing graft.
More likely is for the country and suburbs outside the city to separate themselves from the city. I was in the Detroit suburbs during the 1967 riots and the suburbanites were digging out their rifles, shotguns, and ammo to repel the NAM (black) rioters if they strayed into the burbs.
The problem is that eventually they elect crazy leftist leaders who don’t KNOW they need them. Look at what Zimbabwe, Argentina and Venezuela did to the private sector they needed.
