Probably a bad idea. As it stands now, cloning isn't refined enough to work on humans (as far as I know), and if it does reach that point, the morality will probably become a major concern, as would the security issues that would surface from having clones running around. Plus, the world is already overpopulated enough. On top of everything else, governments or even corporations could abuse cloning, which falls partly into the morality of the issue. Have you ever read the book Brave New World by Aldous Huxley? It might interest you.
