Slavery is only profitable when you get the slaves for free.

Or you pay and free the slaves after a decade or two.

Even if you make them fucking serfs and let them keep 60% of the crop.

Also slaves are bad at noon cash crops.

And crop rotation

Like caracalla and Diocletian knew this in Rome and broke up the latifundia.

System of plantations leading to new plantations

And made serfdom.

slavery was dumb because they didn't sterilize all but the breeders

that's retarded

look up the economics of it

they don't have any incentive to work harder

if they were smart they'd have given every black male a full penectomy/orchiectomy except the breeder, and made sure to select for uglier and stupider slaves

it doesn't work that way man

arabs did it that way

no they didn't

it wa salready done for them

in africa and egypt

if you are khaleed the slave trader in 1200

and you dow nthe nile to the sudan

to get some slaves

your cost is fucking enormous

to buy the slaves

you don't have colonialism and you're a medieval arab. you have nohting that an iron age bantu warrior really wants

but some spices

which also cost you a ton

you have nothing mass manufactuered for almost nothing to give the mfor somethingthat costs what a new car or morecosts today

if yo uchop the dicks off 20 of your new cars

wit ha 90% death rate

you will be broke in one trip

theeunuchs were far and few and guarded the ottoman sultan's palace mainly

and the caliph's harem

there was only one place in upper egypt that did it

ottomans had the white nad the black eunuchs

white eunuchs were balls chopped off only

and not allowed in the harem

blakc eunuchs were random africans

with al lchopped off

good

do it to all africans

but re: trading, here's a solution
