Do schools kill creativity?

This video is about the creativity wich everyone born with, and the education that is teached in every school around the world. Ken Robinson says that the education we learn in our lifes is based on intellectual things, he states the schools prepare us to study at the universities, and to dedicate our life working without creativity.
I liked this video, because I think kids have a bigger creativity than the one adults have, but this creativity decreases as the years pass, largely due to the education we grow up with.
Personally, I would like teach my little nephews to be creative all their lifes, no matter what they do during they grow up, thus they will discover their talents, and enjoy the possibility of working based on them.
