Parenting permits
If you want to adopy a child, you have to go through and long and arduous process to ensure that you're suitable. If you want to foster children, it's much the same. You may not be judged suitable.

If you want to grow your own, it's somehow seen as entirely fine and dandy for you to do it. Once in a while social services or the like intervene (and not always correctly, to be honest), but as a rule no-one gives a hoot.

So - long-term contraceptive implants into children of both sexes from as near to the moment of sexual maturity as possible, with no removal without some serious checking.

And a limit on how many kids you're allowed, too. If you get sterilised and haven't had your quota of children, you can sell your permit.

Good old fashioned eugenics with a modern twist.

Didn't see this
but recently posted very similar idea. If you have a kid and then fail the 'adoption test', the kid's taken off you and you're sterilised.
