I'm sorry that it was distasteful for you to read that slavery has existed in different manners across time with different expectations while still being categorically wrong in what you consider to be a "Shallow" argument. I find it distasteful that you're attempting to rephrase my general condemnation of modern reinterpretation of labor and cruelty in history using period examples across European History as being slavery apologetics. Less Cruel or Labor-Intensive slavery remains slavery, on this we clearly agree.
And it's nice that we agree that society does not consider Children performing unpaid labor in the home as Child Labor, but instead the instilling of personal responsibility, even if the free labor garnered from that child's actions would otherwise cost quite a bit from an employed adult performing the same tasks. Including how that extends, in a farm environment, to feeding animals, mucking pens, grooming animals, and performing entirely separate forms of unpaid labor that an adult would be paid for performing.
It amuses me further that groups like 4H exist that cost money to join in order for the child to perform unpaid farm labor for "Fun" and competition. A situation where you pay money for someone to employ your child with no pay in the performing of agricultural labor... Modern Agricultural Apprenticeship.
Neat!
