It's the result of people choosing freely who they associate with. Wealthy people tend to flock together because they can afford areas with nice amenities and share similar culture to other, typically, white collar people. It's often touted, but Asian students (of some persuasions) tend to be high achieving (on average) regardless of economic circumstances. A lot of that is due to cultural focus on education. There are many ways the gap could be narrowed. One major one is to build mass housing, and stop encouraging housing as an investment. This would lower barrier to poorer families from living in certain areas/less "ghettoization" derived from cost disparity. Of course the nice areas will always be more expensive, but disparity doesn't have to be as wide as it is now. Anyway, many other programs that could more directly attack problem, such as social programs to support regular meals etc for poorer students. But the answer is definitely not putting more funding into education. Anyone expecting good results from that is going to be disappointed, and is ignoring the real world evidence.
