Parents: Must You Be Licensed?

Mechanics need a license in many states. Doctors and lawyers need a license to practice. Beauticians and barbers are licensed. So are teachers in most of the states. Would it not make sense to require the same to be a parent? Is it not more important that the state verify and affirm that one will be a good parent than to declare that one is capable of cutting hair properly? Some think so. Is the very thought of licensing parents a bit frightening? Is it absurd? Would any one ever propose such...
