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.
Have you ever had parents? I realize it's outside the Overton window to do anything about it, but age-based slavery[0] is ubiquitous and the legal default in essentially (I think literally) every country on Earth. It's an even more pervasive affliction than copyright, so I find your ignorance implausible.
0: in the ownership sense; actually using them for forced labor is less common
Please try to address the argument I actually made.
Also, you were responding to:
> a teenager mowing the lawn for their parents
which was about their (owner's) own lawn.
>>>> What's the difference between a teenager mowing the lawn for their parents and someone paid to mow a lawn?
In response to which, I said:
>>> The kid getting paid to mow neighborhood lawns has:
Selective quoting tends to change the context a bit, don't you think?
Then I don't think it really applies to this situation, since just as familial relations are superseding "business" relations in your example, certainly the prison relations change the nature of the business relations drastically.
But I think this is certainly labor, but the distinction between labor and chore is not so clear. I don't think it matters to the inmates, but I found it bizarre how confident HNers are that chores and labor are intrinsically different.
I think we started off on the wrong foot with the comparison. Even government recognizes some difference between chores and labor, as childhood labor is illegal but it's not illegal to have your kids mow the law (afaik).
Its really just an ever so tempting argument of semantics that is at this point distracting me from the real plight of prison laborers. But that's how the internet goes.
Both of them involve "work", but the objectives — the reasons the people doing the work are doing it — aren't the same.
Furthermore, when a farmer's child does chores alongside a paid laborer, what's going on?
