Medieval Latin, from Late Latin Sclavus, from Byzantine Greek Σκλάβος (Sklábos), probably from the Greek verb σκυλάω (skuláō), a variant of σκυλεύω (skuleúō, “to get the spoils of war”).
Slave: Spoils of war!
~40+ million people of modern slavery!
While American slaves in 1809 were sold for around $40,000 (in inflation adjusted dollars), a slave nowadays can be bought for just $90, making replacement more economical than providing long term care. Slavery is a multibillion-dollar industry with estimates of up to $35 billion generated annually.
