"Slaves were the first good that were ever traded between human beings. Ever. They were the first good ever traded.

Native Americans had slaves. Ottomans had slaves. Africans had slaves. Everybody had slaves.

The reason there is no slavery in the West is the British Empire, having practiced slavery for a long time, like everybody else, ended it.

Not only that, the British Empire spent alot of blood and treasure to force the Middle Eastern slave traders, with the Trans-Saharan slave trade being much worse than the Trans-Atlantic slave trade in terms of the number of people who were killed, in terms of the way they were treated, in terms of how long it lasted, it was much worse. And we spent an incredible amount of blood and treasure to end it.

That's the true history of slavery. "
