Corralation/causation. Assume the underlying cause of the discrepency is external to the school (eg. parents' income) (yes, this is an assumption that may not be universally true). It is possible that throwing money at the schools still helps, but just not enough to counter the original difference (either because we aren't throughing enough money at the problem, or we are out of productive places to through money). For instance, consider providing 3 free hot meals a day to students. This helps poor students far more then wealthy ones, and is something we can "just through money at" (nothing in large orgs is actually that simple, doubly so in goverment). But it will not close the gap entirely.
