If no one is actually excluded from any school on the basis of race, and if people therefore can attend the school that is most conveniently located in the neighborhood where they live, and if no one is excluded from living in any given neighborhood on the basis of race, and if no one is excluded from any line of work on the basis of race, thereby giving everybody an equal opportunity to earn the money that they would need to buy the house that they want in the neighborhood in which they want to live, then we pretty much have equal opportunity for people of all races.

But then, you might argue, people who, in earlier days when racial segregation was the official policy in many places, were excluded from good schools on the basis of race and who therefore did not get a good education, are not able to get the good jobs which they need to buy houses in good neighborhoods where their children can then attend good schools and get the good educations that they need in order to get good jobs (etc.).  That's true as well, and this was part of the whole strategy that was used to disenfranchise African Americans in the century following the Civil War, when many people were unwilling to see their former slaves suddenly granted equal social status with themselves.  However, a lot has changed since the civil rights movement in the 1960's, and today there has been enough social (and legal) progress that African Americans who do have ability and do want to advance themselves educationally, professionally, or socially, do have the opportunity to do so without having to rely on racial quotas.  At this time, it is enough to prohibit racial discrimination, and it should not be necessary to use racial quotas to overcome the discrimination of the past.  Or so I believe.  

Weirdly, I don't think this decision is all that out of step with the reality of the direction of education today. "Desegregation" as it currently exists doesn't actually desegregate and just as importantly hasn't made poor urban schools any better. Perhaps this will roil some people, though, and gets efforts re-focussed. The cuts Reagan was allowed to make and Clinton made little effort to reverse have been the real hurdle educators have had to overcome in my generation.

Thinking back to my high school experience, "busing" actually made my school whiter.  We had two high schools, one in the "good" part of town, the other in the "bad".  I lived closer to the "black neighborhood", thus, if attendance was based solely on geography, my school would have been at least 75% black.  It was only about 30-40% black, because the rest of the black students were bussed to the high  school on the other side of the tracks.  I believe some of the richer white neighborhoods where also split between the two school districts, to balance things out.

I guess this avoided a there being a "ghetto" school in my town, but I can't say it much benefited the black students.  Sure, we had AP classes, but there were only about 30-40 students (all white), out of a class of 300, who were on the "college track", who took AP classes.

Really, it was only the intelligent, poorer white students who were the beneficiaries of this system.  Under de facto segregation, I doubt I there would have had access to quality AP classes, as there simply would not have been enough interest among the students from my area of town.  Perhaps that's a racist statement, but I am just projecting based on my experience.  There were no black students in my classes, and few of the white students in my classes came from my neighborhood.

In the end, I can only see this ruling reinforcing de facto geographical segregation, as those who care about their children's education will move away from the poorer (predominantly black) school districts.  But again, based on my experience, this won't amount to a mass migration as the "white flight" of the 60s had already created predominantly white collar communities with their own school districts.  

My guess is that in my home town's school system, very little will actually change, as they will probably find some socio-economic variables that are close proxies for race, and use those to maintain effectively the same racial balance in the school system.
