This has been written about broadly by social historians. This book, in particular, is illuminating: https://press.princeton.edu/books/paperback/9780691133867/wh...

Some other links:

There's also this rather infamous quote by one of the most powerful Republican strategists in the 80s, Lee Atwater: https://en.wikipedia.org/wiki/Lee_Atwater#:~:text=Later%20in...

I won't quote it here but it's very telling.

The Color of Law by Richard Rothstein is another good source on the topic, covering how racist governmental polices played a role.

		That's been on my to-read list for a long time. I've read in brief about red-lining and loosely regulated mortgage providers but it'd be good to dive in much deeper. It's almost always so much uglier and much more deeply dystopian if and when you choose to dig past any surface layer of popular history towards more rigorous historiography.
