Driving requires licensure, even though you can only knock off a few people at a time & do maybe half a million dollars worth of damage.
Carrying a gun requires licensure, even though you can shoot only a handful of your work or school's population before getting taken down.
But what about things that allow you to screw things up for generations? I wonder about how recklessly we leap into things like abusive relationships and electing con artists. (Almost a tautology.)
Without changing existing syllabi (or syllabuses), and with only minor logistical adjustments, it seems promising to institute the following requirements:
* Before voting, passing a 9th-grade civics exam and a course in basic logic & critical thinking. Refreshers required every 4 years, increasing to 6 years after age 35.
* On entering your first sexual relationship, passing an 8th-grade course in effective communication... regardless of how old -- or young -- both partners are at the time. (Because of the strange nature of some pederasts, this should bring some child-abuse cases to light; a desirable side-effect.)
* Before moving in together, passing high-school level home economics (including hygeine) AND a basic financial management course. Everyone does both. Divide the tasks afterwards if you like.
* Before getting married, passing a course in negotiation & mediation. Also adult versions of safety, hygeine, and personal financial management.
* Before breeding, a 6-month intensive course in parenting (including models from Dr. Spock to Attachment Parenting) and developmental psychology. Also, screening for psychoses and serious personality disorders -- not to exclude them (there's no eliminating these from the gene pool) but to provide pertinent training and prepare appropriate backup and support for nutcase, partner, and child.
Wackos raise some very gifted & capable kids, so excluding them from the parenting pool doesn't make sense as a social strategy.
But don't worry, I'm not going to have kids.
