NPR looks at the end of "white flight." William Frey is on there. Really smart guy. I'm less impressed with the WSJ reporter. There's something condescending about this whole conversation. Obviously there's the conflation of the "black poor" with all black people. But moreover there's just this expectation that black people won't be affected by the exact same market forces as white people, that black people won't want to move to a suburb with good schools and big lawns just like white people.
