> Then millions fled America's inner cities in the 1960s due to skyrocketing crime and racial violence.

Let’s make sure we keep the cause-and-effect straight here. White flight was what created the crime, not the other way around. Inner cities in the US became poor, losing their business and tax bases, because of the racially-motivated flight of white people to avoid coloured people. Policies that facilitated white flight were done with the explicit purpose of creating white suburbs and preventing coloured people from following suit. It was not people making rational decisions about crime statistics.
