If all education had remained private, the Protestants would have attended schools that **fully** supported their **specific** religious worldview and the children would not have been subjected to a NON-neutral Protestantism that was generic and lukewarm and run by state-sponsored Progressives.
The Catholics would have attended Catholic schools.
The system we have now can **not** be fixed because it never was religiously, politically, or culturally neutral. Such and education is impossible. And...It has always been a single-payer and socialist-entitlement.
Solution: Begin the process of moving toward complete privatization. Vouchers, tax credits, and charters may help in the change over but should be used with great caution.
