It is unethical to allow children, who are demonstrably not rational actors, the 'right' to 'enter the labor force'.
We can't allow people to make decisions for themselves, they might do something wrong!
I'm glad you agree.
You should form a counter-argument if you disagree, rather than being a cool sarcasm dude. Are you seriously trying to assert that a ten year old child is intelligent enough to understand the risks they are taking on, and should be allowed to 'fire' their parents and become a free agent, quit school, and work to support themselves? Because yes, in many cases, it's wrong to allow people to make decisions that can lead to their utter poverty, illness, harm, or death. This is why we often lock up medicine cabinets and chemical cupboards in homes with children in them- because giving your children the choice to make those decisions (drink the bleach) on their own is pretty abhorrent.
Are you going to prove that a child whose brain isn't fully developed, much less educated with any sort of context about the world, should be allowed to run away from home?
Are you going to ignore that puberty alone floods the brains with hormones that cause mood swings and irrational behavior?
Please address these issues, I'm curious as to your views on them!
Humans in general are provably not rational actors. Given perfect information (which, again, does not really exist in the wild!), there's no guarantee that a person will make a rational choice. If this were not the case, we wouldn't really need a social contract at all.
So, as with PTTG, I'm inclined to believe you are merely trying to be humorous rather than mounting an argument that a pre-teens rights unto themselves are unassailable.
