This is going to sound really bad, this I know but, it's the truth.
Back when the Jews were financing the slave trade and were directly responsible for the importation and sale of slaves/indentured servants to the America's, the slave owners were having an extremely difficult time with the Africans compared to the white indentured servants. 99% of the Africans have never seen something like a shovel or a tool and they were given this shit and were expected to get to work, not knowing wtf this thing is.
The landowners refused to purchase Africans because of the amount of training that was involved in getting these people up to par so, for a while, the Africans were left standing around while the whites were being picked up for top dollar. After a while, the Jews stopped bringing whites over for sale and the only people left were the Africans. The rest, as we say, is history.
