You can’t sell slaves that are lazy and have no skills. Slavers wouldn’t have any use for them.
They wouldn’t know that at first. Later when they found out how utterly useless they are they’d become fertilizer.
Oh, no. That wouldn’t work either. In Muslim lands there is no need for fertilizer. No wonder they detest the Israelis so as they peer across the borders into the Jewish nation they see olive groves, plenty of trees and vineyards.
On their side they have camel dung, dirty hovels (even though Sheik Obama continues to shovel money into their impoverished plot by the billions).
