unnatural growth

I don't know what kind of world we live in. Is it a human world or is it a barbaric, cruel, unemotional world? How can we be so horrible with our own kids. We expect them to perform well in studies. We as society put so much of pressure on them. Why? They are tender human being, yet not evolved completely. They are in process of growing up. They are like a tender tree who are just shaping up. A farmer or mali knows that he has to be soft and gentle towards the growing crops or trees. He know that he can't be rough with it.
