Part of the reason the trend is called "white flight" is that for a long time and in many places non-white people were prevented by bank, municipal, real estate office and HOA policy from purchasing houses or even getting mortgages in the suburbs.
Calling it white flight isn't always an accusation of racism against the people who were fleeing, more against the people who openly prevented people of color from leaving as well.
The phrase "white flight" refers to a 1970s phenomenon where white people repeatedly moved from one suburb to another (often in circular patterns) in order to avoid POC after desegregation and civil rights legislation made suburbs accessible to POC for the first time. This was exacerbated by real estate agents engaging in a race-baiting, unscrupulous practice called "block busting".

No, the 1970s may have seen a recirculation of the original phrase but it is commonly understood that "white flight" refers to phenomenon around the war years.

Your generic suburbs have their own problems – massively artificial, claustrophobic rows and rows of almost identical houses, with zero character and nowhere to go without a car.

On this note, almost the entire Asian population of the Dallas area lives in the suburbs, and those who can afford it are starting to move to the exurbs. Only people without the means to leave are staying in the city because the city sucks.
I didn't move because I'm white, I moved because I wanted peace and quiet. Most of the people I know who live around me moved away from the city for the same reason. Amazingly, non white people feel this way too...
