In the world I ran (
Gattaca-lite), parents would have to undergo extensive training (that began in early education), pass a personality/IQ/EQ/aptitude test, and be pre-approved/pre-authorized in order to have children.
If permits and licences attained via empirical and observational evaluations must be held in order to wield a vehicle and operate dangerous machinery, why less for handling the often asserted (though neglected) "precious" life of a child? The same disastrous result is possible when both unwieldy vehicles and humans are managed irresponsibly > innocents get hurt. In most parts of the developed world, those who babysit or even teach children must be extensively tested or vetted in order to procure the ability to intimately interact with them. And yet, ironically, the same standards aren't as thoroughly applied to those primarily responsible for rearing a child from infancy to adulthood. Doesn't make sense to me.
