Chicago's racial divide

Chicago today is still very much a city divided by race. While blacks and whites in the Chicago metropolitan area work together, play sports together and engage in various other civic activities together, the evidence suggests that they continue to live in neighborhoods -- and to send their children to schools-- that are very strictly segregated along racial lines. And though conditions in the city's majority African American neighborhoods have improved since Martin Luther King arrived in town to protest against the plight of those confined to the ghetto, the improvement has not been very dramatic. This raises a big question: What do you think accounts for the persistence of racial divide in 21st century Chicago? And, perhaps more importantly, what, if anything, could be done to dismantle residential segregation in the city AND its suburbs?
