Well, if you first racially discriminate against a subset of the public, then propose they can set up their own structures at great expense (which only will become similarly prestigious after decades if not centuries, even if they somehow manage to churn out nobel prize winners and presidents almost immediately), it may be a tall order to also demand they be "racially fair".

At the same time you will push out Asian kids from regular Ivy-League school admission processes, after all "they can go to that Asian school".

If you promote the parallel polis, you will get more segregation, not less. That's the very reason you create a parallel polis.
