I struggle with this notion
People didnt have the "foresight" to see this coming.

In cities such as Southfield, Oak Park, Royal Oak etc the rents started getting cheaper and landlords started accepting Section 8 as well.

In my area most of those folks that moved are Black so it contributes to the stereotype that when Blacks move in the property value goes down and the area because a "ghetto" as opposed to benign neglect. There is this idea that Southern Oakland County is now "North Detroit" with all the issues the city has.
