We will never have this because neither side wants it:
Schools do not want it because they lose total control over who they accept. Harvard wants to accept the children of the current ruling class knowing that they will become the next one, and in doing so keeping alive the mythos of Harvard as ruling class incubator.
The other side, which we can call the affirmative action supporters, don't want it either because they see it as a racist by proxy system. And also because it turns out that Asians and Indians (and others too) would do exceedingly well with this system.
