Setting aside for a moment the claim that some public schools are academically excellent, the public schools have become indoctrination centers for political correctness, socialism, educational experimentation, and questionable moral values that many parents disagree with. Yet, those that place their children in private schools are forced to pay for public schools their children don't even use. Freedom of speech and expressions of religious faith have been banned from public schools unless you're promoting Islam or atheism. If the State or Federal Government granted tax deductions or credits for those that don't use the public education system, the enrollment in private schools would be even higher.

"Free education for all children in government schools" is a plank in Karl Marx's Communist Manifesto. Those that keep their children out of public schools should be praised, not condemned for genuinely caring about their children's academic, moral, and religious education.
