The ancient world displays evidence of slavery with especial notice of the Greeks, whose culture was dependent upon slavery.
Though the Greeks had monies and lived within a democracy (Athens, of course) I am struck as to how the Greeks came into possession of other peoples , whether through war or barter of some sort. I've never gone into this but it would be an enlightening study to characterize the roots of slavery in the Greek democracy of Athens.
Closer to home, I see English traders selling peoples brought from Africa to the Americans who by and large were also English. In this case we have the economic or mercantile power of England performing these acts which of course, ended in the loss of 2 million Americans in the war of 1860. The stuff was ameliorated somewhat but there are still echo's of the economics of slavery.
In both cases I would attempt to characterize the cultures and hopefully not snipe though there may be some antipathy to the English which are closer to our times; I don't really want it to look that way and hope to remain as dispassionate as possible.
One point, which stands out to me is the differences in the economic realm between Greece and England. I am led to believe that there is a difference between the Greek approach and that of our near modernity.
Before anyone jumps, I in no way am justifying slavery either during ancient Greece and recent England and its American offshoot. It would be good to clarify the differences and not approach it under one umbrella.
There is one thing I take issue with is the condemnation of a modern peoples (2017) such as the Greeks or English by those who hold the present peoples responsible ; they are not.
Ok, this looks like a rant, but it appears that the human soul is tied into an evolutionary morality to which he is the author and in this no one sits still.
