It's not fallout from a film, it's fallout from SLAVERY.
We freed the slaves, but we still wouldn't hire them to work. They had to go to "Black Stores" and "Black Schools", etc.
Then we wouldn't hire immigrants like the Irish, so slavery turned into a caste system "Black" and "White" are not colors, they are social classes, and white skinned people can be "Black".
Then from there comes people like Marcus Garvey and Noble Drew Ali, which sparked the civil rights movement in the 60s.
People like to think that the 60s came to full fruition and that America was cleansed, but that is FAR from true. They black community was shut down, all the white skinned people were threatened with jail and turned into yuppies, while all the dark skinned people were arrested or left the country so they wouldn't be.
Then came a power vacuum, which allowed for the modern "slavery" that is NOT AT ALL as bad as historical slavery, but still involves making people work for other people to be alive. Organizations that used to feed the poor kids before school, and would watch them after school were shut down, and the leaders (the ones that took over after all the jailing) started selling drugs and using weapons to regulate.
