> What would you think of a boarding school, where there is a meritocratic selection of child candidates from among primarily underprivileged families? The families that are selected receive a payment. The child is housed, schooled, and given rigorous training in a prestigious performance art.

If this is a public, regulated social institution, then I see no problem with it. I don't want to say that children shouldn't be made to do work, but removing them from a family environment to be exploited absolutely draws the line. I just don't know where precisely to make that legal distinction.

And that's fine. We have a fairly good understanding of what constitutes child abuse, it's the removal from the family that needs to be carefully considered.
