Only two options. Binary outcome:
We are all responsible for our own children -- and that includes protecting them from having to work too young or work in dangerous situations. If we don't protect our own children, then they end up either getting stunted or killed, and we have no one to blame but ourselves. That is, after all, the burden of parenthood woven into reality, and also functions as a filter so that stupid parents don't replicate as effectively.
Or, we hand over our parental responsibilities to a bureaucracy, which of course will focus exclusively on process to the detriment of outcomes, as bureaucracies always do. Some stupid, unfit parents will see their children survive that otherwise would not have, but at the expense of children with good parents not being allowed to give them the full advantage of their good parenting that they otherwise would.
The idea that we can find some happy medium, that we can take responsibility for other people's kids without it impacting our ability to parent our own children is fantasy.
Shackling yourself to someone that can't swim is a shitty way to reduce drownings.
Yes. I suppose what those on the other side would argue is that we need to protect those who are too stupid to do the right thing or take responsibility.
Those too stupid to do the right thing or take responsibility = children. That's fine --make me responsible for people who are chronologically adults but emotionally and intellectually children -- but then I make the decisions for them just like parent do for children. That means that they don't vote and they don't get to choose when to replicate themselves. That is my decision to make as the adult who is taking responsibility for things -- with the responsibility comes the freedom.
Can't have it both ways. Can't argue that you are incapable or unwilling to take responsibility for yourself and that you deserve all of the privileges of taking responsibility for yourself simultaneously.
Unless you want an unstable system in which the children steer the plane straight into the ground.
