You’re missing the point.
1. Laws, including state constitutional provisions, can be changed.
2. Blaine is unfair and potentially (Federally) unconstitutional. It discriminates against secular studies offered by a religious organization, whereas Blaine does not prohibit the same economic educational assistance to a private, non-parochial, school.
3. The State does not belong in the educational business anymore than it belongs in the supermarket business. America is not a socialized (at least it shouldn’t be) country. And, frankly, government is a proven failure in the educational business, especially for high school and below.
Let State government’s provide voucher funding for private schools (charter, etc.) and stand up to the teacher’s union thugs and gradually privatize public schools in an orderly, organized, fashion. This way all Americans, rich and poor, can have the ability to choose the best school’s appropriate for their children, rather than only the rich having access to private schooling whilst the poor are stuck with failed inner city public schools.
