I can't imagine that there would ever be an
enforceable obligation to contribute toward the education of the rising generation via private, schurch or home schools (the essence of "private, church, home" is that it IS private and voluntary.) But as I said, the fact that parents are paying all the costs of a workable future society, and your generation would reap an ensemble of tangible and intangible benefits, ought to inspire some thoughts of inter-generational solidarity.
Solidarity. That's a good word in anybody's vocabulary.
