Wanting something doesn't imply benefitting from it, though. The world is full of things that try to exploit your wanting mechanism without providing benefit (or even enjoyment that matches the wanting). You can say that an individual's job is only wanting things that will be good for them, but that's an awfully hard job. Society should help with that, e.g. by teaching children to distrust dreams that promise too much.
