What's the biggest thing taught in the classroom? It isn't things like reading, writing or arithmetic. And I'll sim[ply point out one of them here. You can find others when you think about it. But... all kids of elementary age would love to be out in the real woods of nature, running and jumping and living life to the fullest. But they are taught to SIT, in the classroom. Of course, there are other government/big-business kinds of indoctrination.
