This is our philosophy through the thoughts of a daughter who was raised like my kids are.
It's all about self education, not schooling.
Notice she is not a Christian per se, but its the way we raise our kids, either way. We even give freedoms, so they can explore their environment, whatever subject they want, to encourage their curiosity and passion about things they wish to do. She might want to stay up to work on a game MOD or something, that is fine with us.
Even if you're an Atheist, I wish you would reconsider HOW you view things, and consider unschooling your children. We do, and the results are awe inspiring.
Kids need to be kids, inquisitive, passionate, and seeking. Your method (one that promotes pubic education) crushes that. Did your method REALLY teach you critical thinking? It seems you preach to the choir of public education. You would get a good pat on the head from your Shepherd for doing so. Because like Pavlov's dog, you were conditioned to desire that. That system of yours crushes potential of the individual. Doodling in class will get you reprimanded, or sent to some authority figure for punishment, in my house its celebrated and encouraged.
As a business owner, admittedly, I would seek to hire the valedictorians of the world. They make things easier for business owners like myself. I know they would be good sheep for my company.
If that is your goal, then great, seek it.
