De-schooling

I certainly did not and probably will never have the courage to not send my children to school at all.
However, I noticed very clearly, specially with my older offspring that school diminished his mental abilities noticeably. He used to be very, very observant at age 3, noticing minutae and arriving at theories regarding these minutae which were totally logical within the framework he had. An example is that I am taller than my mother who in turn, is taller than my grandmother. With this observation, he told me seriously one day "you know, we all grow taller and taller till a certain age, then we start to grow shorter again till we become the size of babies."
Once in school, he stopped telling me these profound theories. I assume he stopped thinking that way. Still I would send him to school if I had to do it again.
However, a few parents are now experimenting with not sending their children to school. I don't know if it is a good thing or not. If your kid has an inclination towards -say - sculpture and is spectacularly good at it, then he/she can make a living out of it......it will work...maybe he can at a later date become apprenticed to some artist and learn sculpting. But what if your child is not spectacularly good at anything...just an ordinary kid? Then with no formal education, not knowing many things we take for granted, how will he/she make a living.
I notice that those who opted for this are quite well to do themselves. What do they think their children will make a living out of?
