Sad thing is, we've got laws in this country to stop you using underage sweatshop labor. You can't make a kid lose his childhood toiling away to make jeans or sneakers, but there's little to stop an ambitious family from tossing their talented kid onstage and working them to the point where they don't HAVE a childhood...
We 'grow up' in school, on the playground, and doing 'family and friends' things. Deny a child that, and who should we point the finger at when they grow up to be bizarre and unstable? The parents, for doing it, or us, for not caring, as long as we get great music out of it?
Sadly, most of us simply pointed the finger at 'Wakko Jakko' and laughed.
