I took a POV here to get people to stop looking at everything like a commodity. It's very US capitalist that if you can buy it in a catalog and have Amazon Prime deliver it, what's the problem? Seriously - you could offer whale meat sushi served with rainforest hardwood chopsticks on an ivory plate sent via diesel refrigeration truck to your house and people would still buy it. Humans are awful. However, value of human life? In a way far more interesting/sad. In short order you pretty much covered it. Slaves were valued at billions of dollars, enough that America was willing to pay the cost of 700,000 men's lives to argue about it, even as what we're discussing is chattel slavery, which values only the output of a person as their maltreatment shows the slave is not valued for being human.
