CTL,
I understand the realities you mention. I am talking about an ideal view of how things should be. There are so many discussions on how to deal with side effects of over-centralization. This is like chinese government in Beijing issuing edicts about lack of healthcare beds in a remote province. Same happens even in Great Britain with a PM spouting number of new beds built in some town that the MP just inquired about – due to central ownership of the issue. These issues are intractable, and each “cure” creates additional “inequalities” that yet another government office will “resolve”.
Jewish educational system, as described in Bava Basra, suggests a local system with each town being responsible for hiring enough teachers. you are using a threat of segregated schools to oppose improved education of most of the country, including Jews – as if most of schools are not segregated anyway due to segregated housing. If you are so serious about the issue, and I respect that, then you should propose a limited solution for that without holding back millions of kids. for example, allow vouchers for schools that are in areas where there are no mixed areas, or where schools are not segregated. This would allow most of your state to move ahead in education. You yourself received wonderful religious and general education, how do you feel that others are not able to afford it?
I would say this affects even those who can afford it – can you open a Jewish school that will serve only rich children and hope to have good Torah and middos to happen there? From Gemora to Chofetz Chaim in 1920s Poland say that rich kids are not learning Torah well, talmidei chachamim will come out of poor children.
