It is an inevitable consequence of the algorithm run by parents who raise academically successful children: each year, move to the school with the highest proportion of other academically successful children. (Not to say this is responsible for success but it’s definitely correlated).
Start with a perfectly even distribution of family characteristics between schools. Make a few random swaps. Now some schools have just slightly more academic-success density than others, but this is enough to attract some other successful families.
Run that out for a few cycles, and the differences quickly become extreme and permanent.
Even if SF could attain that even distribution, it’s inherently unstable.

Rejecting students just means another school will have to pick them up so what is the gain to the overall education system in doing this? If this was removed then the system would be much fairer. Putting children with similar learning abilities in the same class-room is better for everyone. Placing an advanced child with a challenged one can hold both students back.
