I'd say it's worked as expected in the areas where it's actually implemented. In most suburbs, there is a racial mix that's (probably, I don't know the exact metrics) close to the national demographic, and in those areas the culture is fairly homogenous. I grew up as a kid in the military and lived in multiple suburbs during and after my parents' service. The schools, neighborhoods, and local businesses all had what felt like a fair spread of various races, and I never observed any race-based hate. This was across portions of Mississippi, Oklahoma, Ohio, and California. Heavily urban areas seem to shift toward race-oriented living areas, where I think there's a lot more animosity between races because a white person in a predominantly black area or a black person in Chinatown stands out more and generates concern that they aren't a part of the area's culture.
