For the good of the child. Not for the good of the state. In this case, the state properly intervenes in the sacred relationship of child and parent only to the extent that it may be necessary to defend the rights of the child from a parental default of fundamental duty. However the state has no right to demand that kids go to school because it will make them "good citizens" or economically productive.
Whatever just powers state enjoys to intervene in private life derive from its mandate to be our servant -- not our master.
"However the state has no right to demand that kids go to school because it will make them "good citizens" or economically productive."
If we say it does, it does. We are the state. If we want to require service of young people to make them better members of society, that is quite within the constitution.
"For the good of the child."
Hi, we're from the government, and we're here to help you.
The state does not have rights. That includes the right to indoctrinate children in government schools and forcing Christians to pay taxes for blatantly anti-Christian institutions.
