> It is worth noting that a world where children from broken, impoverished (etc.) homes are not disadvantaged is a world where one cannot advantage one's own kids

This is such an uncreative, broken, zero-sum, awful line of reasoning. One can shift up both the bottom and top rungs of a scale simultaneously, so that there would still be advantaged kids despite there being fewer children from broken/impoverished homes.

In fact, such a thing has been done but not necessarily for morally good reasons either. This uplift is exactly what was seen when schools were desegregated in the South and the bottom (black schools) were uplifted: the emergence of private expensive religious schools that were effectively white-only, raising the uppermost advantaged bar as well.
