> No, because children don't have a right to work.

I'm not sure what point that's meant to make, but it supports what I was saying. You'd never be able to derive that exception from:

>>> Well, the UN definition of "Human Rights" includes the "right to work"[1].

There's loads of different competing rights, exceptions to those rights, and other social practices that need to be weighed to make a judgement a situation like this. Focusing too closely on reasoning about this one "right to work" ignores all that, and thus leads to less than enlightening conclusions.
