Earlier quoted context omitted.
> Nobody is arguing you should have to pay kids minimum wage for doing chores... "Chores" and "labor" are categorically different things, and the motivation for the former isn't usually "offsetting their upkeep", so much as it's "instilling a sense of personal responsibility". This is a specious comparison.
What's the difference between a teenager mowing the lawn for their parents and someone paid to mow a lawn? Furthermore, when a farmer's child does chores alongside a paid laborer, what's going on?
1. The right to say "no" without repercussions beyond "not getting paid".
2. Significant statutory protections regarding exploitative treatment.
EDIT: There's also a large body of statute defining what is and isn't okay in the family farm situation.
