I am going to post this article from last year which covers a lot of the topics of re-segregation of schools through unique methods.

To touch on your point specifically, I am sorry you had such a poor experience. You are right when you say that social programs need to exist so that children are not hungry at school. Education is supposed to be the great equalizer and yet America has provided education almost only for the rich and has consistently attacked the poor. But I also feel bad for the kid who had to steal from you every day just so that he wasn't hungry at school. Education and wealth are a combined, intractable problem in a capitalist country, but there are hundreds of places making the problem worse.
