Controversial evolutionary theory of Darwin
Biblical slavery is often falsely compared to slavery in the Antebellum South. Biblical slavery was often voluntary to pay off debts. It also offered an alternative to living in poverty, and was a means of providing for your family (after all, there was no welfare system). If you owed someone a debt you were unable to pay, you could voluntarily sell yourself into slavery on a contractual basis as a way of repaying that debt.
