Slavery is economically irrational. The risk of losing a William Deming or a Tim Cook because they were enslaved is far more damaging than the benefits of guaranteed cheap manual labour. We have an economy where a 1 in 100 worker is much more productive than the other 99 if they are allowed to make their own decisions about where they contribute. Funnily enough; the people with moral objections to slavery gained ascendancy at roughly the same time it became economically irrational. And started winning wars against slavery-tolerant societies because slave-based economies couldn't possibly compete with technology and industrial processes in the hands of free people.
