A good point in general, though I'd add that, 1) slavery has been around for a long time and in many cultures family members are/were treated as property, especially women and children; and 2) for much of history[1] power, including ownership of land, has been concentrated in few hands, who often were not very kind to their subordinates. I wonder what the historical distribution of self-employed (including subsistance farming) vs employed by others. [1] Of course it depends how far back we go in history. Until 10,000 years ago we all were hunter gatherers.
