I think it just has to be understood that "choice" means choice for some but not for all, and society has to be OK with that. (I'm not OK with it).
In a system with a mixture of public and private schools, the public schools will always be a necessary feature of the selectivity of private schools. Not only to accept "problem" kids, but also to operate in areas where it's not profitable to run private schools, or in cases where private schools run into financial and management problems and must be bailed out.
So it's not so much that the private schools are "better" but that they both function as interdependent parts of a system.
On the other hand, there will always be a need for special education... mainstreaming all kids in one classroom hasn't worked very well either.
