Possibly because of the amount of pressure that the parents put on the children. Just because the parent likes music doesn't mean that the kid has to like music too. As a result of this, the child will end up having a hatred towards the musical form and will never even try to give 100%, and without trying no-one can know that they have talent. A solution to this would be to make it only optional - but then again there'd be the lazy talented ones who don't want to try anything
