it's also worth noting that one big contributor to white flight was the desegregation of schools.

Big city school systems would now have to integrate people of color with white children. There were plenty of people who did not want this, and unscrupulous realtors would use blockbusting to generate huge profits, where they basically scared white people into fire selling by telling them minorities would come into their neighborhoods and integrate their neighborhoods, and then turning around and selling to minorities at inflated prices. https://en.wikipedia.org/wiki/Blockbusting

Suburbs were effectively havens for white people since most minorities could not afford to move into suburbs, and their separate school systems became effectively all-white as a result.
