You can tell a 10 year old to clean the house, weed the garden or wash the dishes. But tell a 10 year old to help dad at work and suddenly it's illegal.
If getting children to work is bad, then housework should be treated the same as any other work.
Work is inherently exploitative. A parent-child relationship is not (most of the time. I know exceptions exists). That's why it doesn't make any sense to compare work and housework.
Pretending otherwise to make a precious point is absurd. You know it.
Not really. Not until they're of an age where they can legally separate from their abusers (at which point they can usually work independently). Until then, they'd just be another source of income to the abuser with few independent legal rights.
